Title: 1999 5.3 L GMC Motor and Transmission
Post by: turbodoc on May 22, 2013, 11:17:01 am

I have a 1973 Chevrolet Cheyenne Super 10 that originally came with 454/400. Does anyone know if I can put a 1999 5.3L engine and transmission out of a GMC truck into my 1973 without modifying he frame? Thanks

I believe you just have to install different motor mounts, move the transmission cross member, and use stock camaro (2010) exhaust manifolds to fit inside the frame rails.

This post pretty much documents the whole process.
