I thought would share my latest fuel injected engine swap project with you all. Took a 1993 C1500 Sportside with a 4.3L V6 and stuffed a TBI 7.4L big block in it. Funny little project for my father in law. He is taking it to the paint shop next then treating it to a set of 18” Coys wheels.
Highlights… (believe me, there was a lot of head beating against the wall along the way)
4.3L on its way out.
4.3L next to the 7.4L.
4.3L mounts just before removing them
Isn’t this nice, engine mount nuts inside the boxed frame so the lower control arms must be removed in order to replace engine mounts. Real bad deal if you have a GMT400 4x4 as the torsion bars would need to be removed as well.
What a hassle just to replace engine mounts
Ready for an engine
Taking a ride to the exhaust shop
Duals + Flowmaster 70 sans cat
Called a friend that owns an AC Delco repair center and got hooked up with a new Tach instrument cluster.
Old non-Tach cluster
New Tach cluster
Youtube test drive.

Got a few small things to dial in before it goes into the paint shop. The A/C line needs to be reworked in order to connect to the accumulator. Tried to use a 1996-2000 accumulator but those hosers at GM changed the threads from SAE to 27MM in 1996 so no easy way other than cut the hose free at the farrell at the compressor and run a new hose to the accumulator with new crimp clamps. Then I am sure something else will pop up that needs tweaking.
