4.3 Bellhousing

i AM PUTTING A 4.3 IN A M38A1 AND WOULD LIKE TO USE A SM465 OR SM420 TRANS. I'M NOT SURE WHICH BELLHOUSING, YEAR, WILL FIT WITHOUT HAVING TO USE AN ADAPTER. I WANT TO USE A HYDRAULIC CLUTCH SET ALSO. I'M ALSO LOOKING FOR A SCHEMATIC FOR THE 1993 4.3 TPI HARNESS.

 

Please dont use caps. It generally refered to as yelling in most forums.

As for the bellhousing I know its been discussed in the past, have you tried searching for it???

For the wiring heres a schematic I posted up a while ago. http://www.earlycj5.com/forums/showthread.php?t=18014&highlight=4.3+wiring

 

Sorry about the caps. Thanks for the images of the wiring harness. I spoke to Novak adapters and they said use a mid range(year wise) bell housing. Not an early or late model but an in between year. They wouldn't elaborate anymore than that. They wanted me to buy their's.

 

Here this thread has the info for the bellhousing..

Sm420 uses a small hole bellhousing, the Sm465 uses a large hole bellhousing.

 

If you find an SM420 and need a bell housing let me know. I’ve got a cast iron bell housing from an SM420 sit’n in my garage. I couldn’t use it ‘cause it’s so big it interfered with my through the floor pedals.

 

I appreciate all of the info. I will let you know how the things are going.

 

The bellhousing I went with for my 4.3 swap is a factory Chevy hydraulic unit which was available from 1985-1991 (or so my sources say) on the full size (C/K series) and smaller (S/T series) trucks with SM465 4 speed transmission. It took me a while to find one but I feel it was well worth it.
