Ok, need some info. Will a big block bolt up to a small block tranny/transfer case? Or is there a big block tranny?
cheers

Yep.

da-burb · 01-21-2006, 11:11 PM

you are in luck, as far as the bolt pattern goes, they both canbolt up to the same tranny.

The 230/250/292 straight 6's and 4.3L V-6's are the same, too. Don't you just love Chevy's?

big blocks didnt come in 4x4s so its not quite as simple as popping one in where there never was one. but if you do a search there are lots of threads to help you with the process.

Big block will bolt up to a small block tranny, you will need motor mounts.

Have you got a motor located ? What year is your truck ? I may be able to help .

Not that it helps in this instance, but the 2.5 four cylinder has the same bellhousing as the inlines,small blocks and big blocks too.

I dont have a motor yet, the truck that i am building is a 72 chevy 4x4. I was kinda thinkin 427 but they are hard to find. Might have to put in something else.

I've got a 72 GMC 4x4 with a 396 BB, 700R4 tranny, and a 208 transfer case for running gear. If I can be of any help, let me know.
