thinking about looking for a doner car w/ a 200R4 that i can pull the OD trans for my 70 SS 350. were there some models with beefier transmissions or were they all equal from the factory? do i want to stick with the stock converter? i have a 200R4 in my 70 wagon but dont know what car it came out of (80's malibu? monte carlo?). i really like the lower rpm's on the freeways. my wagon is a column shift and because of the linkage the shifter is unable to shift into the lowest gear. no big deal but my camaro is a floor shift. will i be able to shift into the lowest gear?
