Re: My official big block combinations page (viewing is mandatory)

454 .060, 2 bolt.
.250 pop-ups on thumb rods/arp rod bolts. Looking for 10.25-1 final static compression.
Scat crank or alternate.
781 or 049 heads pocket ported and chamber adjusted for compression to be named. roller rockers mandatory.
Edelbrock Performer RPM (standard or air gap), Weiand stealth, or Weiand Action-plus manifold. These are my three choices and would use any of the three.
The 60204 Lunati Voodoo is all around kick butt for a brutal street bruiser. If a bit more lope is required use the 60205 but the RPM range is higher than you may wish. The 60204 lopes, not like my 69, but a nice throaty lope and will run your vacuum brakes. Advance the cam 4 degrees and the dynamic compression will come up quite a bit and the throttle response will be even a bit better yet.
Hooker 2255 comp headers, 2" prim with 3 1/2 collectors

Darryl-I also have a buddy who says, I should, and it is beinicial for some big blocks to be advanced 4* for more snap. Do you on yours and what is the negative. Also, do you lock your timing out?

Dave, that baby has to fly!

That is identical(less headers, we used 2255 hookers) to the build I helped my brother do on his 73 SS 454 chevelle, even the cam. It rips.

The only difference between his SS and my Laguna motor is the cam (286 Powermax VS my 60204 Voodoo) and the intake (Edelbrock performer VS my Weiand Action-Plus). His 73 has 3.42's vs Lagunas 3.73's and both have 2200 stalls.

Dave. your's has to be a easy 12 second ride. Sweet.

 

Re: My official big block combinations page (viewing is mandatory)

Gents,

Looks like the kid done mde up his mind!:hurray:
Maybe a 350 1970 Elky/th350 vs 350 68 Elky with TKO 5-spd grudge race before the engine re built and swapped in.:boxing:

Part-throttle downshift from 2nd to first after a low-speed 90-deg corner, there is some power now boys and all it took was major gear swap!!!!

Something sane like a 60203 Voodo, roller rockers not really required. Something 'big' like the 60204 VOODOO and roller rockers would be good idea. The 60205 VOODOO rollers would be a requirement. 60205 is stupid-big BTW. Think this is valve-train trouble waiting to happen. Really think the 60205 is bracket/street intimidation, not street.

Good intake choices Darryl. Brett, $120 in that ad for a Perf RPM is "OK".
I prefer to see wht I buy vs mail-order. Hate surprises. I've used Edelbrock products new and used since 1977. I'd run 750 cfm 3310 w/upgrades for street duty and have an 850DP for week-ends

 

Re: My official big block combinations page (viewing is mandatory)

OK, looks like Brett hs sent messge to Doug re the 60-over pistons w/HD rods and ARPs. Scat crank is $240, Eagle Crank is $276. I've no preference here.
Am sure Darryl has a good used one too. Your votes:
A: Scat
B: Eagle
C: Good stock crank

Think we're talking budget, longevity, moderate usage. Brett kept saying low RPM. I don't want to make him something he really can't drive due to bad manners or excessive/excessive bad manners and very poor mpg. Typical bad manners and poor mpg are just things ya must live with. I do not see Brett heading N of 6000. Some of the larger Berg cam choices do seem bit excessive.
Brett, counting on you to tell us more of what you are looking for.

BTW, RatVette even with ext manifolds sounds much like Darryl's 69 Chevelle. Sounds like it will blow off the mufflers......

 

Re: My official big block combinations page (viewing is mandatory)

I'm not going to say a word except I agree with what ever Darryl says...:yes:

Oic, taking the easy way out hmm? I guess you will always be right that way.

Ok so I picked up the 60 over pistons and rods. They looks to be in pretty good shape. Have the ussual carbon build up but no chips or scores. The rods are the thumb ones that Darryl raves about. Has arp bolts as well. He left the rings on the pistons, and they looks pretty good, but with the cost of rings there is no reason not to put new ones on.

I will start compiling a list of new parts on my summit wish list and will be having the fellas look it over.

The plan for this engine is to be a street torque monster. I want to have the ability to drive it daily, be reasonable on gas, but also have more torque than I know what to do with it. I will not be going over 6k rpm. It HAS to have 450hp and 500 ft lbs minimum, these are just benchmark requirements I have set.

 

Re: My official big block combinations page (viewing is mandatory)

Brett,

Good goin getting the rods and pistons from Doug Z.
I'm looking at one of those rods and the lower dome H426P slugs I got from Darryl. A fit less oomph than what you got but I plan to use the closed chamber heads I have. This will make a sweet combo for me.

I'm more than anxious to do some testing with my new gears.....
Nope, this is not pick on a BBC powered car power here, she just runs so much better......I'm gonna find that kid I bought the Elky from b4 he graduates and heads off to school. I'm gonna scare the crap outa him with little "firepower demonstration."

 

Re: My official big block combinations page (viewing is mandatory)

Remember Brett has a TKO 5 speed. Not an auto with a 2200 stall.

My vote is firm on the 60204 voodoo or comparable quality cam from another manufacturer.

Want to play with horsepower numbers? Here's a cool link at TCI that has some HP calculators for 1/4 stuff.

Re: My official big block combinations page (viewing is mandatory)

Darryl,

I am fully aware that Brett has a TKO 5-spd.
I'm also very confident that Youth and Enthusiasm can be overcome by old age and treachery! I'm also getting hints that there is more power on tap than I figured, unleashed the beast. First gear ends very quickly.....and I was on it 1/2 throttle...think Dennis down the street has an old Sun tach....

Ref Rat Build-up
I'd probably not go over 60203 in a "street Elky":boring: :boring:
I just think Brett would want a bit better manners and more low-end.

I'm gonna try to link with Mark GOTAGO today. Show him the slugs and rods then take him around the block.....

GHK

 

Re: My official big block combinations page (viewing is mandatory)

Let us know asap on how the Elky runs out when you mash it. You have been more patient than I would have but it sounds like you're ready to cave to the HP gods and see if you can shove the peddle through the floor boards. LOL!

 

Re: My official big block combinations page (viewing is mandatory)

FRYNTYR,

Yes, patient, always conservative, always plotting!
Round trip to Arlington and initial test run, I totaled 220 miles plus of which 110 would be after the gear swap. Thinking I'll have 200 mi by FRI for sure.
First gear seems terribly quick now! Elky is in 3rd before crossing major intersections.

I was looking up the F-M H426P slugs last PM, just a Google Search.
One hit took me to the Team Chevelle archives. Guess what was building?
that's right, 454 w the same H426P slugs, the budget 228/238 cam, Perf RPM, and a Holley 3310. Think the thread was from 1999...... dude wrote the engine had more torque than you could ever need! Looked some more, data says .100" dome, was thinking all along .133". So, my 101cc heads and .1000 dome, not 10.58:1 but closer to 9.8:1--10:1CR, actually more suitable for pump gas premium compared to RatVette where some Booster is still a good idea.....

 

Re: My official big block combinations page (viewing is mandatory)

Brett if those piston rods are used, REPLACE THE ARP BOLTS. Used rod bolts are not the way to go.

Welcome to the dark side

 

Re: My official big block combinations page (viewing is mandatory)

I'm curious about the timing also, I'm curently running a Unilite mechanical distributor. I've got it set up with 22* initial timing @ 700 RPM, with 16* mechanical advance, all in at 2200 RPM=38* total. Seem's to be pretty good, alway's thought about trying to get up around 42, see what it's like.

Dave, 22 initial won't hurt at all. In fact it may be more responsive, period, if your compresion and gas combo agrees. Kinda depends on how big your cam is but If it were me I'd stay away from playing with more total (the 42 idea).

My rule of thumb on vacuum advance: plug it, don't use it, it will just cause more grief than good on a thumpy motor. Vacuum advance is intended for economy purposes and to run with low initial timing settings. If you want economy, buy a Honda. If you want power and ease of tuning, leave the vacuum advance plugged and tune your initial and total advance to match your combo.

 

Re: My official big block combinations page (viewing is mandatory)

Man with all this brain power, there's got to be a monster out there waiting to be built.

With his 5 speed, couldn't you go a tad more radical? As long as the cruise RPM was in the lower range of the powerband, would a little more cam work on the street? I'm asking cause I want to put an OD in mine and build a streetable 496. I shouldn't have broached the subject with Darryl, between that and these threads, I'm gettin' the fever.

George, will try and get down to see you tomorrow.

 

Re: My official big block combinations page (viewing is mandatory)

With the 5-spd, better 1st gear ratio, in theory, yes, can go more radical.
Thing is, that monster .68 OD drops the cruise RPM bunches....down so low big duration cams don't work well....lugging at 65 or cruising nicely at 80. This is ok for Montana, Spokane, Coalville, and Pullman but asking for trouble in W WA.

With 5-spd you can run less cam, have better manners,,,let the 5-spd gearing do the work.

Earlier I gave a bad number for CR with 101cc heads and the H426P slugs.
I said something too low. Believe.133" dome 10.58:1, a .100" dome would give me around 10.4:1......perfect.

4* advanced takes some off the top end power off the overly large cams we run to beef the low end/midrange power. Some cams are ground with this so tread lightly. Other side of the coin is that with yet more bottom-end grunt, traction games become serious.

 

Re: My official big block combinations page (viewing is mandatory)

Thanks Darryl. I will pull the cap and chech the springs.
BTW it is a hydrolic roller and the guy who owned it locked the timing at 36* for street and race.

 

Re: My official big block combinations page (viewing is mandatory)

If it's locked you can leave it but it's a small enough roller that it would be a little more street friendly if it had some mechnanical advance in it.

 

Re: My official big block combinations page (viewing is mandatory)

I was just stating that's how he ran it. I have my advance hooked up...for now...

 

Re: My official big block combinations page (viewing is mandatory)

oh,,ok. my bad. Wheww!!

 

Re: My official big block combinations page (viewing is mandatory)

Frank,

Darryl is right once again. Most aftermarket distributors come with heavy springs. Guess this is so they can hit you up again for a few more bucks to buy a distributor tuning kit. RatVette uses one Med and one light spring; 10.75:1 CR, .542/.542" 235/235 deg dur .050" 111* sep. I've tried about every combo of springs and wts on the seat of the pants dyno. I have a brass bushing on the adv rod to limit the advance. I probably have too much advance so will be looking for a way to close the adv slot a bit without removing the distributor and brazing the slot.

 

Re: My official big block combinations page (viewing is mandatory)

Frank, what kinda distributor You running?

 

Re: My official big block combinations page (viewing is mandatory)

Frank, what kinda distributor You running?

Something with a ugly tan cap that doesn't match my motor...:clonk:

 

Re: My official big block combinations page (viewing is mandatory)

Well, that don't help, I got all the spring's and a chart as to what they set the advance to......but it's all for a Mallory.

 

Re: My official big block combinations page (viewing is mandatory)

Well like I said I bought the pistons and rods. I just bought some valve covers off of ebay. I am watching an auction for an intake on Ebay right now, it ends in the morning. Supposed to go look at brand new headers for $150, $450 new from summit. Was going to look at them tonight but he has not called yet. They apparently have 2 pea sized dents, but with 2" size tubes it shouldn't matter. Also supposed to go look at a 454 4 bolt block 049 with oval port heads and a steel crank tomorrow.

I have been putting everything I can think of as needing on my wishlist on Summit, after its all said and done, I am almost positive I will be below $3k. Overall I would say I am doing pretty well with the prices for what should be a screamin' BBC.

 

Re: My official big block combinations page (viewing is mandatory)

What kind of carb should I start looking for? I'm thinking in the 850 cfm range, also thinking holley, but what do I know? It needs to be easy to tune and reliable, I dont need a super power house making for the strip.

 

Re: My official big block combinations page (viewing is mandatory)

The Street Avenger's are a great carb, easy to tune, and good to go outta the box.

 

Re: My official big block combinations page (viewing is mandatory)

I'm not positive but Ben might have a brand new Holley he'd part with.
You'd have to ask him to be sure.
What's it got Ben, 50 miles on it?

That would be perfect, I dont need new. Why did he take it off after 50 miles?
