This is my 1977 GMC Sprint just after getting it home from California. Drove it back to Colorado and let me tell you I will never forget that ride. It had a huge hole in the muffler and kept overheating. I stopped in NV and removed the thermostat. But it kept boiling over every time I turned it off. So after a stop in Utah I just left it running all the way home.

The original engine and transmission are gone and a 290hp GMPP crate motor and rebuilt TH350 have taken there place.

This is the old engine. Its now in a rock crawler.

And this is the new power plant. GMPP 290hp 350.

Dropping the new engine in place.

Engine swap complete.

The interior gauges.

The B&M 2800 stall converter and new flywheel ready to go in.

A Weiand Pro Street 144 Supercharger is in the very near future (its been sitting on the bench forover a month)!

And here is is...

Here's my engine with the intake manifold removed.

Supercharger manifold installation.

And the final product.

She really screams now!!!

Now I just gotta find a cowl induction hood.
