ok this is what i got so far, an edelbrock rpm airgap intake, roller rockers, holley 600 cfm double pumper, mallory distributor, and a set of hooker headers. now my problem is that i bought a set of gt40p heads, and im looking for the right headers to fit my 66 mustang. oh i found out by opening the engine that its not stock anymore, its been bored .030 over and it has a high volume oil pump but still with the stock crank.
