Default 383 newbie

Hi guys I have been lurking on this forum for a while now so I guess I should join up. I just finished a 383 build for my 52 chevy pickup truck. It is a 383 stroker 11.5.1 compression, 6.0 rods fully forged rotating assembly with a set pf pro 1 200cc heads and a comp xr288hr-10 hydrolic roller camshaft. Induction is 2 600 holleys on a ported edelbrock tunnel ram intake. I was just wandering if anybody has built something similar to this? I was thinking that it would be around 500 horsepower, does that seem like its in the ballpark? I am worried that I went to small on the heads, and have access to a set of pro 1 215's and was wondering if it would run better with those? the engine sounds great and has crazy throttle response but am I leaving alot on the table with the small heads? thank you guys very much any info would be appreciated...

I'd ditch the tunnel ram too.......put the 215s on it and a good single plane with a good 4150 carb. It will more than likely make more power in the rpm range you are wanting to run it. The 215 head isn't nearly as big as you think it is..........

I agree with Jake, I would think the single plane and 4150 would be the first and the 215's as a close 2nd.

I would recommend the 200 heads, you will build a quicker power band, and a better torque curve. Since your cam is a hydraulic roller, the 215 heads will offer a higher top end horsepower which can exceed 6500 rpm, especially with your 11.5 to 1 compression. If you add a set of high rev hydraulic lifters for past 6500 then use the 215 heads.
Just my opinion
