I have read pages and pages of text here and either can't find my specific answers or the links are old and dead. I have a 1974 3/4 ton longbed. Currently has a 454 with a TH350/203. I picked up a 700R4/208 combo from an 85 longbed that had a 350cid motor. I really want the deeper first and OD. Had planned on waiting on the swap but there is a guy with cash in hand that wants my TH350/203. Here are the questions: -Will the torque converter in the 700R4 work fine with my 454? (came from a 350) No idea what the stall speed is. -Is there a cheap set up to get the TV working(stock parts) or is it best to run the $80 kit from bowtie overdrives? -Is there wiring info somewhere for the lockup TC or is the $109 kit from bowtie overdrive the best set up? -How do I hook a speedo to this thing?(I honestly did not look but think it is electric) -Anyone made a 203 shifter work on a 208? How? -Anything else I need to know before I yank out my perfectly good TH350 and make my truck into a planter?
