Comp cams xe268h for 318

Stock 68 block .030 over 71 J heads with 2.02 valves. Wouldn't make good power until 2500 rpm then it came in .
I didn't like it as I want a street car .

In the rebuild, I'd bet something like the Felpro standard head gasket were put in, which are quite a bit thicker than the originals. Just that change would make the Static CR drop from the ACTUAL 9.7-9.8 from the factory down to around 9.2. So AJ's numbers are likely higher than what you really had for cranking pressure and V/P.

I gotta root around Wyrm's info on how the factory actually measured 'advertised'....IIRC it was at .008" lift?? (Wish I could get his info on that matter memorized.) Meaning that at .006" it would be more like a 274-ish cam and driving more towards being sluggish in the lower RPM ranges. And if the stock cam had no ground in advance like almost all of the aftermarket hyd flat cams do, there is another factor; it would go in retarded typically 4 degrees versus most aftermarket cams if installed dot-to-dot.
