I just put on a set of heads & was wondering if you guys could come close to my rated H.P. Here is what I've got.

71 350 bored 30over
stock bottom end
cam edelbrock #710 hydralic specs advertised duration /Intake308d/exh318d @50 234/244

I figure its making around 600 horses(haa I just kiddinf thanks in advance for your help

The edelbrock packages are advertised a little optimistic. For the most part you have the RPM cam and the Performer heads. You should be in the 'real' 370-380HP range.

I ahve a 99zz4 crate motor that runs 355hp.. And has bigger cam. and heads. So I say you are around 300hp

Imho, the E-brock RPM cam need's at least 12 to 1 to run it's best AND I don't care what E-brock says..

I tend to go by this!!

250 = 8 to 1 CR.;

260 = 9 to 1CR.;

270 = 10 to 1 CR.;

280 = 10.5 to 1 CR.;

290 = 11 to 1 CR.; and

300 = 12 to 1 CR......

I figure all of them are down-playing the correct compression ratio's needed b/c of our now cat-pee gasoline won't let us run cams much bigger than 270 degree jobbers, but they still want us to buy bigger ones....
