Bell housing question

I have a 1969 C10 that we are switching from Inline 6 to V8. I had a question on the manual tranny bell housing.

Do I need the bell housing with the rear mount pads? I have seen aluminum bell housings that do not have that mounting surface.

The tranny is a Saginaw 4 speed out of my friend's 1969 Camaro.

Thanks ahead of time for your help!

If you already have the factory crossmember under the bellhousing you could run a rear mount bellhousing with the 4-speed. That is how a manual V-8 truck would have come in 1969.

If you do not already have that crossmember, I would pick up an aluminum bellhousing and install a generic transmission crossmember under the tailhousing of the 4-speed.

If you are going to use the bell housing trans mounts the cross member for the bell housing mounts are different for the I6 and V8.

Re: Bell housing question

Here are a few more pictures of the 6 vs 8 manual trans cross member . I did this conversion on my 67 short bed frame to mount the 350 v8 in the correct position .


the V8 cross member is on the left with picture of the V8 engine perches . changing cross members with the cab on the frame is tough . You can drop a small block in using most of the 6 parts and a lot of guys do to avoid all the extra work and a bunch of new parts to do a correct 6 to V8 conversion install .

Re: Bell housing question

If I were swapping an L6 truck to small block I would keep it in the 6 cylinder position. That should give a better weight balance to the truck and also allow for a shorter driveshaft if going one piece.

On top of that it is a lot less work than removing rivets and finding donor parts. As mentioned above, it would appear different than a factory optioned V8 truck.
