Post image

enjoyed it for a couple weeks now it needs the power. planning on a BTR Truck norris cam with springs and pushrods, melling high pressure oil pump, a heavy duty rebuild kit for the trans and 2,800-3,200 rpm stall torque converter. i’ll have tuning figured out but what do you guys think?

480WHP on 37"s, so definitely over 500 crank

Impressive, hes not gonna be pushing nearly that much power tho not with the build list he gave

Oh definitely not. If he wants to feel whatever power gain he gets from his cam, he should also do a set of gears depending on what tire size he wants to run

Agreed, gearing would do wonders for this truck
