Spray WD40 or similar stuff along the intake/head join, if the exhaust smokes or the engine speeds up, you've found the problem. I use ether starting fluid, no mess to clean up, but many are too faint-hearted to try this.
Nobodys answered my question? WHY do I want a stall converter? I want this truck to move like a normal vehicle, I do not want sudden surges, it is nearly impossible to put this vehicle on a trailer. I do not want to have to put a ton of rpm into it while in gear to move at all. Hell it would be nice to idle up the trailer...........

Higher stall seems to me would have ot rev even higher to move.... I think the problem is I dont need a stall on here at all. This is not a race or drag vehicle... strickly show.
