Re: Need to know a 383 w/TH350 in a 1964 GMC truck longbed?

If the I6 is a 230 or 250, you don't have to change the engine mount brackets. Just bolt new engine mounts to the small block and drop it down onto the frame brackets. As for the TH350, you will have to remove the bellhousing crossmember and install a trans mount crossmember. A trans crossmember from a '63-'87 truck will work.
