Re: Need to know a 383 w/TH350 in a 1964 GMC truck longbed?
New motor mounts and trans mount, and most likely have to lengthen the driveshaft.
I had a 305 v6 and 3 speed in my 61 gmc (little different as the frame is different than yours) but when I did my 383 and th400 I used a aftermarket tubular motor mount from a later gen truck and found a factory auto trans crossmember. Had to get my driveshaft reworked with a slip yoke and a different yoke for the tranny.
