Well my buddy at work wants his 350 72' Nova in the low 12's. He currently has a 3200 stall in his TH350, and 4.11 gears out back. We have to use his current 350 shortblock wich i believe he said has flattop pistons, and we cant get too expensive and shes gotta run on pump gas. Im thinking 200cc Pro Topline heads/64cc combustion chambers for around 10:1 comp semi-budget roller rockers, Performer RPM from a swap meet or a brodix 1016 dual plane, 650 speed demon, and an Erson solid as follows 282/290 adv. 246/254@.050, .510/.510 lift, on a 108. out some 1 3/4" hooker s. comps and a 3" exaust. What do you all think? I dont know that whole stall converter deal real well so im kind of lost there. Hows that sound? Any suggestions on cam, converter etc?

Looks good to me. Ya might stick a 3310 750 Holley on it though. 650 is a bit small for 3" exhaust, 200cc runners, 12's, etc...

650 is wet flowed. Demon wet flows there carbs. so in reality its actually 750cfm, maybe a little more.

If you want it to perform well there specific parts you can't scrimp on.The Heads, Camshaft, and Stall Converter are those parts.

ProTopline Iron Lightning 200cc castings are a good choice.

Skip the Semi-Roller Rockers:
There are no big gains here (even if you get 1.6's) other than looking cool when the valve covers are off.

Skip the Erson and Edelbrock cams:
Spend a little money here or you will be sory.
A little more money spent here will be well rewarded.
Chose a modern grind like the XE series from Comp Cams or a nice grind by CamMotion.Though CamMotions recomendations are generaly a little big.Or ask the advice of UDHarold on this board.He works for Lunati and designs cams.

If you have flat top pistons and 64cc heads you will end up with around 10:1-10.4:1 compression with a thin steel shim head gasket.You should use a solid cam to achieve your goals.

Skip the Brodix HV1016 intake.I don't think there will be any big gains over similar intakes that can be had for cheaper.A used regular old Performer RPM or the Holley Street Dominator 300-36 will serve you well.There is no need to go with a Air Gap RPM either.No big gains will be made.If you end up with a converter that will flash to 4000 RPM a used Victor JR would also work.Don't bother looking for a port matched one.More money for no big gain.

The converter is one of the keys to achieving your goal.Do not scrimp here.You will be sory.B&M and TCI will work.But if you want top performance look elsewhere!
Good companies to look at that will not make you lose a nut are Coan and BTE.Do not chose the Street/Strip models.Call them and give them specific detailed information on your combination.Go with the racing converter they recomend.It will probably cost about $300. more,but it is worth it.Be prepared to give them detailed info on your combination before you call them.
BTE will probably be cheaper.Contact Oldani Motorsports (Steve) on this board for a good price.Chose the cam first.

If you don't already have the Speed Demon 650 skip that too.A 3310 750VS will also work but a 750DP will not cost that much more and it will lower the 60ft (key to low ET's) much more than the VS carb.A nice unbutcherd used 750DP will work very well.
If you want a new carb look here http://search.stores.ebay.com/search/search.dll?query=AED&srchdesc=y&sid=7567982&store=Tires+N+Parts+Inc&colorid=4&fp=0&st=1
The AED 750DP Holley for $399.95 is a good price.

Thrasher...dont take this as an attack, but even if somone payed me i wouldnt put an "XE" cam in any motor i have anything to do with. Erson is a good cam company,and have a good selection of cams, heck if its good enough for John Force its good enough for anyone id say.
Now as far as the Brodix intake, theres an article somwhere on it VS the RPM and it whooped the RPM through the entire RPM range and i believe this was with a cam that was about 250@.050 thats why i suggested it, but ive never seen anyone run it first hand yet.
As far as the rockers go, maybe i typed that wrong graemlins/clonk.gif , i was thinking of a less expensive aluminum roller rocker, not a "semi-roller" Just somthing that isnt on the level as say my crower enduros. And i got ya on the Oldani motorsports thing. We both live in Waterloo so that works out well graemlins/thumbsup.gif

Erson doesn't design those cams for John Forces engines.They are designed by the engine builder and then special orderd.

If you don't like CompCams XE grinds good for you.I find it kinda refreshing smile.gif
I don't believe that they make the best grinds either.

Don't take this the wrong way,but I wouldn't use an cam designed from Erson if you paid me :D

Like the Edelbrock they are old and slow ramp designs.
So to each their own.

I would suggest asking UDHarold or checking with CamMotion for newer designs.

So whats your deal with erson, ive had 1 other person i talked to say he didnt like them, for only one reason, they were a super shop cam for years.... any personal expierences or friends expierences?

i have to agree with thrasher on most of this. don't know anything about the brodix intake, but i do know the rpm/air gap rpm both work very well and if a test suggested that another intake kicked them around, i'd be leary of who was doing the testing, brodix, maybe? ;)
convertor will make or break your combo. definately with a loose convertor and 4.11 gears you should use a 750dp Holley.
why would you not run the XE cams? Erson makes good cams, but you're not getting the same product John Force gets. :D
i don't see low 12's being a problem with what you are planning, as long as you get the right convertor, which unfortunately won't be inexpensive. i know guys that have had great success with ATI, Coan, Houghes, and JW convertors. personally i'm running a Coan, but i wouldn't be afraid to run any of the other brands i mentioned.

I haven't run any of Ersons stuff but I have had several friends that have tried them.Including one that did work at Stupid Stores.

All of them found better performance after they switched to cams by either Crane or Comp Cams.

As far as the intake goes.I have the Brodix HV 1016 article in front of me now-It's called Manifold Destiny-Super Chevy July 2002.If you think 11HP at 6200 RPM is worth $125.+ go for it.

Well here goes on the XE cams. Aggressive lobes are good to a point. When you get to the point of the XE cams you have a better chance of flattening on startup first. if you get it broke in, they're notorious for chatter wich ive been told is the exaust lobe slamming shut. THat aggressive of a cam is hard on all valvetrain parts and could potentially cause a premature failure of somthing and the extra power YOU DO GET FROM THEM isnt worth the rest of it in my opinion. I wont knock there power potential but from all the people ive heard complaints from i wouldnt even browse their catalog. Now i know John Force gets a different cam than we all do, come on guys graemlins/clonk.gif , but i doubt hed back a less than great cam company, that guy could go to anyone he wanted and theyd grind his cams, so why is he not at comp or somone else???Ive personally never run an erson I currently run a Howard right now but im going to try a "lunatidyne" this spring and see how she goes. Also im not knocking the RPM, its obviously a good diverse manifold. I do believe it was super chevy that did the dyno test on the intakes, ill ask my buddy wich article it was and see if i can post some info on it.

Look at my last post smile.gif

I'm just saying that your money wil be better spent on something else that will be much more rewarding like converter,headwork,and camshaft.

Thrasher, what were the extra power gains all across the borad? HP and TQ? And are you talking about $125 on top of the price of the RPM or are you talking about a $125 price tag???

You can get a used Performer RPM for $80-$90.
You will be hard presed to find a used Brodix HV-1016.
The cheapest I have found them for is $215.(on Ebay) not including shipping.Direct from High Velocity Heads (HVH) it's $219.

The testing started at 4100 RPM and the Brodix has a 1.5 ld-ft lead on the RPM.
At 4200 the Brodix has about a 5 lb-ft over the RPM.
At 5000 it has 7l b-ft over the RPM,and it makes small gains untill it is about 11 ld-ft better at the HP peak of 6200 RPM.

Just wanted to add something real quick. I wouldn't recommend using those aluminum roller rockers. I've heard bad things on them and was just reading a comparison between the aluminum and steel roller rocker arms. The steel came out in 1st on all the tests. I guess comp makes a good set of steel ones. Just thought i'd mention that.

John Force probably runs Erson cams because they give him a good deal- or give him the cams for free. just another form of sponsorship. if Crane or Comp or Lunati gave hime the same cams, he'd swear by them, as well.
altho, it would be cool to have the "John Force Series" cam that will give you a guaranteed 6000 hp..

He also moved to Ford when GM wouldn't give him insane sponsorship money for his dual car program.He went to Ford and mentioned that no one was running their bodys.This was their chance to have their product represented at the forefront of the sport.They gave him insane cash and the rest is history.

Remember when Kenny Bernstein was sponsored by Duralube graemlins/clonk.gif
He was also sponsored by Erson graemlins/waving.gif

Here's your sign.
