Tweet

yeah i bet it was for a different reason lol. in my truck I currently have 4.10's in the rear with a detroit locker. next on my list is the suspension work, as well as dropping the BBC in the truck.
i figured, id go with a slightly lower duration cam, get some monster torque going, should be fun

with the info you gave, and i will agree with mr. erikson it is under carbuarated with the 650 carb, so desktopped with the 650 is 425 hp, 445 tq, and with a 750 carb, 440 hp, 451 tq.

i went to holley and put my info in, they ask how many cubes you have, and a bunch of other stuff, brakes, electric, or manual choke, etc. And they reccomened a 650. What do you guys think, maybe a 700???? 750?
The 572 has 620 HP and runs a 850 demon.

hey moon eye, can u run this on desktop dyno??? Or if anybody else has it?
the same info as above but with this cam instead, and run it with the 650 first, and then try the 750 carb. Thanks!
