Mark B · 11-22-2010, 02:48 PM

I have a 1970 with a 3 speed and 250 six and am considering a swap to a TH350 that I have in a 1970 donor vehicle, which is also a 250 six. Is that the right direction to go? Or it it better to swap to a 700R4? Would a 700R4 it fit the six? Is it an easier or harder swap than a TH350?

thanks very much
Mark
