Big Block Factory Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Were there any 4x4's with a Big Block? I was told they didn't make any but figured this would be the place to check.

No 4x4 came from the factory with a BB. 350 was the largest engine.

Thanks for the info. Anybody know a reason why?

70cst is correct, no big block 4x4s.
I believe the reason is not much room under the hood by the firewall. The 4x4s had the engine sitting in the rear mounts because of trans case and front diff locations.
Doesn't mean it can't be done however...

I know it could be done, I just didn't know they weren't produced from the factory. I'll do a D-Max swap before a BB.
