My 700r4 has gone bad. I am in the thinking stage of pulling the engine/trans and doing a V8 conversion while I'm at it. The truck has almost 200k miles, yet paint and interior are very nice. My thinking (and searching) leads me to as many questions as answers. We all know the problem of CPI. The limitations of V6 efi upgrades..... Anyway, can anyone here give me the been there done that advice? I don't want a hot rod, but definitely wouldn't mind 300hp. More is better IF it is reliable enough to drive on trips, etc. I don't want to jerk the truck around but would love for it to be fun to drive.
