Asked by OneSlow350 Mar 13, 2020 at 09:59 PM about the 1990 Chevrolet C/K 1500 RWD

Question type: Car Customization

I have a 1990 Chevy c1500 with a 350 small block currently in it. Can i take a
454 big block and directly bolt it up without have to change anything? Is it Plug
and play or does something have to be changed or modified in any way?

Not plug and play, lot of stuff has to be swapped to go from small block to big block. Motor mounts, bigger springs, upgrade to bigger brakes, tranny, exhaust and headers, ECU, to name a few.

The 454 was an option which means you can do this with factory parts but not necessarily small block parts.
