700R4 ?'s
I am once again considering making a serious modification to my truck. Right now i have a TH350. This would be adding a 700R4 automatic tranny, out of a '88 up GM car/truck. I have several questions:
1.How much will i have to shorten the driveshaft, and how much will i have to move back the tranny crossmember. 2.Will i have to modify the tranny crossmember to bolt a 700r4 to it? 3.Will my stock collum shifter work? 4.Will the 700r4 speedometer drive work with my speedometer? 5.Which would be better, a lockup converter or a non-lockup converter? 6.How much of a jump in MPG should i expect? I get 10-12 right now with 3.07:1 ratio gears. ------------------ Lucas "Another proud owner of one of the coolest trucks ever built" drop_shift@hotmail.com My Daily-Driver: '72 Chevy LWB Custom/10. Rebuilt 350, roughly 300 HP thanks to a 204/214 duration cam, Edelbrock Performer intake and 1406 carb, headers, and 40 seires Flowmaster mufflers. Ochre with a white top. Lots of fun .
