I have a 1970 Boss 302 with the original block, crank, intake manifold and
Cleveland heads. The Crane solid roller cam, Holley 650 double pumper
carb and 10.5/1 pistons are new. MPG port plates are installed for both the
intake and exhaust to smooth out the midrange and the car runs well on the
street with no stumbling. What are the pros and cons with a setup like this
and would better flowing modern heads be a better choice for this engine as
installed in an ERA FIA Cobra?
