'93 K1500 Big Block Swap

Mar 23, 2014
I have a '93 K1500 Silverado. It's the Standard Cab z71.
I'm planning on building a 427 BBC and planting it in with a 4l80e.

I need a rough idea of what I need to make the BBC fit in the engine bay?
I've seen a truck like mine with a 502 in it, so I know it can be done. I just need to know how.

Any and all thoughts/information/ideas/recommendations are appreciated!

Pull small block, bolt in big block. They came factory with them, so it will fit. need all the accessories off a factory 454 truck, or lots of fab'n to get stuff to work. Also need a stand alone ECM for the tranny to shift, or go with a manual v/b.
