Another engine swap question 400-305-454 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

If it is an '82 it should come out mounts and all and bolt in. But an '82 is not a TBI 454, that didn't start until '87 I believe. Is it a '92 maybe? If so, the motor will work but the mounts may not. They did make suburbans and 1-tons in square body style until '91. Is the 4-speed a manual or is a 700R4 automatic?

The TBI 454 is not a real power house but is still pretty thirsty. The heads are not all that great for performance. I think you are much better off with a nice 350 or 383 myself. Even better, do an LS conversion.

Need more details on your donor truck.
