just thinking about the future and was wondering what can be expected from going from a 468 (595lift) oval port 2.19 1.88 valves 9.2 comp. dual plane 850cfm motor to installing a 6-71 blower? i realize i would have to change the crank to steel and get better rods,lower the compression and gaskets/rings. as a mentioned in the future$$$ but what can be expected if down correct? what have i missed? what are the general feelings about streetability?
