I Got a transmission from a machanic and it is out of a 1991 chev van The van had a 350 in it. Well the motor blew and the van was scraped.The tranny is supposed to be a TH 700 it has 1-2-3-OD.I am hoping to use this in my 54 P/U Would it be stronger than a 350 or a 400 tranny.The motor I am useing is a 400 hp 350.I dont know alot about trannys so any help would be great. Thank :confused:
