Question 350 Build Up

Ok everybody, I am looking for opinions and input on building up the 350 for my '56. Here is what I am looking for......

400+ rwhp on pump gas
reasonable compression ratio
w/o boring or stroking the engine

Starting out with a stock '73 350.

Thanks.

David

Ok,well how about this then......

If I used the Vortec heads and the dual plane vortec intake on the 350, what kind of cam would you all suggest using? What kind of power would I be able to get from that?

I know there are people on here that can give me input on this build up, and I don't think that 400 rwhp is asking for much from a 350. I just need some input on what the best way to build it up would be.

Chevy High Performance Magazine recommends the following (July 2002) issue.


1.Chevy 350 CID with standard GM flat top pistons
2.Pro Topline or World Products Sportsman II
200cc 64 cc heads
3.Edelbrock Performer RPM, or Holley Strip
Dominator Intake
4.Holley 750 CFM Vacuum secondary or equivalent
Carb
5.Headers 1 5/8” primary tubes
6.Flowmaster or equivalent quality muffler
7.The Cam recommended in the article is
a.Crane PowerMax H-288-2
b.CompCam Extreme Energy 274


After getting a reply from “Chevy High Performance” Performance Q&A section:

I have a heavy car like yours a 4000# Monte Carlo, Kevin McClelland Recommended that I use less cam such as:

CompCams Extreme Energy 262 or
Crane PowerMax 272-2.

He said for a heavy car, more torque is important so the smaller cam will give better low End torque and only cost about 15 HP at the top end about 6000 RPM.


Hope this helps.

Joe
