Which stroker kit for 470" b-engine
IQ is doing a set of RPM's for me as we speak and also having a custom solid roller done up for me. He's talking some serious HP numbers too.
As I type this I can hear Cody grinding on them right now.
He just finished a set of MP 452 aluminum heads. They are just like the RPM heads but with the straight plugs. These 452 used the stock port window and the stock 2.14/181 valves and flowed,
Lift...........OOTB IN/EX.............Ported IN/EX
.100................70/57....................75/60
.200..............145/112.................153/128
.300..............205/163.................218/172
.400..............245/197.................265/211
.500..............260/217.................295/242
.600..............276/231.................309/264
.700..............281/239.................322/280
So as ported they have a good 650hp potential. Yours of course will flow better than these with the improvements we are making.
