with that cam you need a 3600-4k stall. that cam would love a 4k

Out of the 220/220,551,551,112 and the 220/224,581,581,112 can u feel a difference on wot

Not a lot but the 220/224 will pull harder in higher rpms

Like from wat rpm to wat will it pull harder

it should pull up to 6400-6500 rpms but wont be a big difference from the 220/220 just a little stronger.

Cuz now I have the 220/220,551,551,112 cam installed on the truck but i am askin opinions to c if i stay with that cam or swap it to the new 220/224,581,581,112 cam

Depends on your plans on build. Id do the 220/224, 224/230, or 224/228. Something with a split will perform better if youre doing after market heads or going FI.

Wat does fi stand for
