Hello, I recently got a Chevy Chevelle from 1970 in which a 1972 engine was installed. My question is now, how can I get out of such a 165 hp engine the original power of 1970, i.e. so about 300 hp (on the rear axle)? Is that possible with relatively little effort (about 2000 €)? I was thinking of another camshaft (so what like the CompCams PART #K12-234-2, www.compcams.com/Cam_Specs/CamDetails.aspx?csid=84&sb=2 ), and a different suction bridge. care, a double pipe exhaust system, HEI distributor and it is a noble brock carburettor (500 CFM) installed. Are these things enough to get about 300 HP from this engine or what is still necessary? Should one start with the heads or the pistons etc also do? Thank you for your help Greeting Felix
