That chevy cam was also ground to match an 11.25:1 static compression ratio. I have seen people use it in 8.5:1 engines and it wouldn't pull a greasy string outta a cat's butt.
With the '151' Camshaft, you needed >
* Compression {11.0-1}
* 'Fuelie Type' Cylinder Heads with the 2.02" Intakes
* The good #200 lb. Load-Rate Valve Springs
* Good Exhaust {2.5" Manifold Header Outlets}
