im tossing around the thought of redoing my top end on my oval port 454 ( well 460 i guess since its 30 over) since i didnt build the motor and i wont feel comfortable untill i at least do the cam and intake and check out the heads ive got, ive heard great things from edelbrock about the power package like 540 hp on an oval port 454, anyone used these componants together or seperatly? at minimum i want to do an intake/cam swap and am still leaning twords the rpm cam and intake. any info appreciated

It's kind of an unspoken rule on Team Chevelle that the Edelbrock cams leave alot to be desired. There are much better cams out there. What are the specs on the motor? If you're not sure because you didn't build it then it may be a good idea to wait until you pull it apart and then select a cam once you know what you have for compression specs. What's the intended useage?

i know a little about it, its 10.5:1 comp. ported and polished oval ports ( by wes king, but i dont know how much they were worked over)supposed to have eagle rods and some sort of aftermarket pistons. right now its got a hydraulic roller cam/lifters/rockers and a wieand old school duel plane manifold ( model 180 2p) im guessing the manifold isnt providing the flow that the heads are asking for in the higher rpm range that it swings too. carbs a holley 770 street avenger. i drive the car daily.

To me this is a no brainer. First, find out what cam you have and consider going up to a more aggressive Hyd Roller. Reassemble with a better intake (assuming these are large oval ports).

1st off,the RPM BBC cam is not the grind you need for strong street/strip performance.
You all ready mentioned the motor has a hydraulic roller currently..what are the specs? You'd swap out your current roller for an Edelbrock flat tappet? :confused:
What about the rest of the combo? What gear,tranny,etc. ?
May be you need to dial in what you currently have before spending money..what are your performance goals?
I'm not trying to sound sarcastic,you just need to know what you exactly want.

i am trying to make sure what i have matches up, i know the best performance is attained from componants that compliment each other. im definitly going for a street/strip car. the only reason i asked about the edelbrock package was its supposedly proven performance, my cars a few cars quicker than my friends 02 SS camaro with pcm tuning and full exhaust so i imagine my heads are ported pretty well, but i dont know for sure, would i be able to choose a manifold and larger roller cam by just guessing how far the heads are pushed out? how would i match the cam i get to a manifold is it done by the peak rpm range?

Hey fellow Turlock resident. You since you already have an idea of the compression you have and what you want to do with it, pick a cam according to how you want to use it. Sounds like you are breathing pretty well through those heads, so pick a cam that will compliment your compression and flow, but at the same time something that is designed for your application. Mostly street or strip? If you are going mostly street cruiser probably consider something like the edelbrock performer RPM intake. If mostly strip or you desire higher end performance go with something like the single plane holleys. Those are my $.02

oh sweet another turlock memeber! i do drive the car daily but i dont commute to the bay area or anything, im shooting for a mid 12, im guessing it runs something like a low 13's right now, my friends car ( ss) runs 13.30's- 40's so thats what i base the ET on. i know ill have to get my suspension/traction in order to get the mid 12's but that will be done soon ( ssm lift bars and edelbrock adjustable upper control arms, slicks or drag radials)im ditching my little 2200 stall and going with a 3000 so i would like to match the cam and intake for mid to high end power, any suggestions?

Elky,
I am running a 3000 converter in my '69 402/T400/3.73 car. I will most likely drop to a 2400 when I install the new 454 motor. Biggest drawback to a 3000+ converter is having enough RPM in the motor to keep the converter locked up when running the car. I have found my setup needs a 1-2 shift at 6200 - 6300, if not the shifts are quick but soft. You need to determine what cam you have and also need to get to the track and get a real 60' time. Your setup may already be mid 12's when dialed in, you just don't know it yet.

I would take your car to the track and find out what it runs..JMO and experience.
I wouldn't assume it runs mid 13's either
You don't need adjustable upper control arms if you have the SSM bars

I built what was essentially a copy of the Edelbrock power package. Same bottem end and Edelbrock roval heads. I used an Ultradyne solid cam and a Dart single plane intake with a 950HP Vac Sec Holley.
We made 565hp @ 6400 with 540 lbs/ft @ 4600.
In my 3500lb Nova it ran a best of 10.9 @ 122 and that was on pump gas.
I do not think the Edel package would make it's adv. HP on the dyno we used.

Funny you should ask,,,
I am doing a 496 with that cam & those oval heads as we speak for a magazine article hence the EDE heads & cam :D

I just took the heads off the flow bench & got done profiling the cam.
The heads are fair for what they are, nothing special, I have seen very well ported 781's that would equal them but the cam actually surprised me.
It is advertised as 302/304 @ .006 lifter rise or close to that & 224/232 @ .050 & 114LSA
It is actually 284.9/288.2 at .006, 223.7/232.6 @ .050 & 114 LSA.
If someone wants the flow numbers I can post them later.

Since I used to have those heads....I'd like to see the numbers.

mr 4 speed, why wont i need the uppers if i have the ssm lowers, im not very good at the art of building a suspension, in the past ive always just slapped some slicks on and used alot of vht in hopes that it would hook, im just assuming it runs mid 13's because i pull 2-2.5 cars on my friends ss that runs mid 13's. decenmber 4th weather permitting will be the first track day for the car, after this weekend ill make a few g-tech runs and work on shift points a little in preperation. by track time ill have ssm's and drag radials or slicks. no matter what this combo runs ( unless its alot faster than i think) im going to want to redo my top end, thats why im planning and askign questions now, so i know what to get when im ready

Question concerning the SSM bars (from Jegs). I have a set on my 67 454, the bars are not adjustable. I had to install adj. uppers in order to keep the pinion angle in check. Do you have adj. SSM bars??? Also, I have just finished rebuilding with RPM intake, Isky hyd cam, Speed Demon 750, 3000 stall, 3.7 posi. Runs like a raped ape. Had a RPM cam but was too big for my intended use.

Mike, those numbers are actually about 20CFM higher at each lift point above .300 Lift than what Chevy Hiperformance had tested at. I think the cam you have there is the Torker Cam, not the RPM.

That's because they were tested on a 4.530 bore & the heads will almost always pick up with the bigger bore.
The numbers were very close to advertised which in itself is somewhat of a surprise as I have tested quite a few heads & have found more than a few to be lacking, especially in the low to mid numbers.

The cam is the Torker RPM or whatever they call it but & is the one that is called for with the oval head package & it has advertised seat timing of 302 on the card but is a more reasonable mid 280.

Didn't realize there was that much of a difference in the test bore. That's alsmost 10% in the low-mid lift range. Learn something new everyday.

ssixt7, are they the jegs brand or actual ssm bars, i saw those jegs ones but they arent adjustable , ive never seen the ssm's but have heard from reliable sources those are the ones to go with

Not always but with some heads it makes a huge difference,, also these heads had some hand blending done to them by Edelbrock which may or may not be normal as I don't use Ede heads much. But being as they are destined for a magazine article & dyno test,,,,, ;)
Also, this is not about a huge HP engine it is about a reasonably priced torquey street engine that anyone can duplicate without breaking the bank. ;)

I would love to bolt a set of the Brodix Race Rites on this engine but don't see that happening as the all the parts came from other manufacturers & I don't have any control over what goes in or on the engine :(
I will talk to the gentleman who is writing the article & see,,,,
