I have a good friend who will be retiring in a few months. He has a 1990 2wd Chevy work van that he wants to donate to me. The van has a new throttle body 454 with a newer 700r4 tranny. It has a 14 bolt rear but not sure which one it is or the gearing at this point. All the stuff would transfer over to the 77 Blazer ie. the radiator, trans cooler, etc. Im not sure about the fuel tank at this point. The motor in the Blazer is tired and cant seem to hold its fluids. Im just waiting to grenade the thing one of these desert trips and to be honest I don't want to even fool with trying to find the leaks. Ive changed everything out including the rear main seal, one piece pan gasket, new fuel pump gasket, valvecover gaskets, even a new oil pressure sending unit. I'm sure I can find a place for the 700r in on one of the hot rods. But what do you guys think about hooking up the newer 454 to the well used TH350? The TH350 was rebuilt about 10000 miles ago and still seems to shift well. The shift kit still slams hard when it shifts. Should I be looking for a 4x4 700r or a 4x4 TH400? I'm really wanting to get the 454 in the rig then I will have no excuse not to build my Expo trailer that I have been dreaming about for several years now. Any thoughts or ideas on a tranny swap? Wisdom from your experiences?
