Inliners International Forums General Discussion Drive Train Sm465 to a Gmc 302

I have a '55 270 that I pulled from the original pickup. I have had several transmissions in it from the old four speed in my '53 Chevy to a T5. I made an adapter for the T5. I ran a Saginaw 4 speed for years and had no problems. I don't know if there is a difference in bell housing length or not but I doubt it. The difference in length in Chevy and GMC engines was made up in the front motor mounts. Everything back to the rear axle is the same. Lots of Chevy V8s have been bolted into old GMCs. There may be different length input shafts for the SM 465 if needed.
