Team G' isn't the best intake by far, but I think someone would be crazy to say you couldn't make over 500 horsepower from heads that flow 265CFM, 2" headers, big carb, and a pretty healthy solid' camshaft. Compression ratio is over-rated IMO, and you make more power from a conservative CR with the best tuning on the street, than detuning and retarding timing to run on pump fuel with high compression..
