This Old ’65 Goat Gets a New (LS1) Heart Transplant

Having a classic car for a daily driver is likely one of the coolest things that can happen to any enthusiast. However, it does get a couple of notches cooler when its a father and son project. The 1965 Pontiac GTO shown here is very cool on both accounts.

Gaining inspiration from last year’s Run to the Hills in Pigeon Forge, TN, the Mistretta boys – father and son – decided to update the GTO with a more modern engine. With some hunting, they found a donor car and pulled the 5.7-liter LS1 engine out.

The classic 389 Tri-Power Pontiac mill was removed and sold for someone else’s project. The job is done now and looks great, but there were a fair share of challenges along the way. Sorting out the right oil pan, motor mounts and exhaust system topped the list.

While things were apart, they also fitted a 6-speed Tremec T56 gearbox and revised the dashboard using modern Auto Meter gauges. With some hot cams and mid-length headers installed, this goat now puts down 376 RWHP.

The classic 4-spoke Boss rims, with their charcoal finish, contrast nicely with the silver paint, and the red line tires compliment the red pin striping.

This is certainly a class act and demonstrates that there certainly is life after 45, even if you are an old Goat.
