Make a move to the roller? Specs?
I guess i know the answer already, but what value do you put on cranking pressure? Any value to trying getting it toward the 150-160 range at the sacrifice of some duration and/or overlap?
Managed to make two pulls today with the EZ heads, roller cam, Victor 440 intake and 850 Mighty Demon. 544 LB-FT and 655 HP. We had 521 LB-FT @ 4800 rpm and 521 LB-FT @ 6600 rpm with a peak of 544 LB-FT @ 5100 rpm.
On an iron head I always raise the top of the intake port window by about 3/16 of an inch, to remove the small jog, and smooth the flow. Top of intake manifold port has to be raised also, to match the head. My question is, IQ 52, does this need to be done on a Performer RPM head when using it with a Perf RPM Intake manifold? Ok thanks. Great job on the 440 torque and horsepower levels! Have you put any of these engines in a 1/4 mile drag race car? What kind of ET s are you seeing?
