IR set ups & longer runner will idle MUCH better with a large cam, much better drivability, low & midrange torque is much better
I agree, but AFAIK the only stack injection nearly large enough is the Crower for BBC, which has 2.90" butterflies.
Depends on how much power you want, the set up I have flows way more than I need for the power level I am at now, 2.9 butterflies are in the 1000 + hp, I am in the low 600, street car, overdrive A/C . Hilborn does make the 3" bore, My butterflies are 2.4375,the runners are 2.5 id, do the math my intake valve is 2.14, the id of the intake seat is 1.94
