Sell the 340 or build it

Irr3333: That’s about where I am. Even in my 84 d100 the 318 rev limiter is set at 5500. It just an old truck but me and my son have a blast in it. Hell. I bought the motor, a518 trans, headers for 700 bucks. Came out of a wreck 90 model truck. We slapped a Ford 9 inch with some 3.73’s and a true TrAc. It’s the fastest trash truck in town lol. We call it rusty.
