Pontiac Solstice Build with 427 V8 Engine Swap

This Pontiac Solstice was the subject of a project build at Hot Rod Magazine. With the additional help of General Motors Performance Division, the two joined forces and utilized the 2 seater’s rear wheel drive platform as the basis for a 7.0 liter, 427 cubic inch V8 engine swap. Since neither take any assigned task haphazardly, naturally everything in the car was torn apart and rebuilt around the new crate engine using mostly all GM parts numbers, including suspension and brake upgrades to match it’s new found horsepower. Continue with us on the next page for a closer look…

Over the course of three online issues, Hot Rod Magazine and GMPD worked together to make this possibly the most bad ass Solstice ever built.
We never thought we would have uttered anything close to the assembly of those words linked together, but this thing honestly looks like an absolute blast to drive.
In fear of sounding too cliche, do we mention any resemblance of this to a modern day Cobra? At 3,000 pounds, a heftier one no doubt, but the same basic concept certainly remains.

The 6 speed manual transmission was sourced from a Chevy SSR, along with a Cadillac CST-V rear differential and brakes.

Aside from the custom built radiator and a few other small bits, the rest of the build can be recreated using the GM parts numbers provided in the list below.
Can you say “roller skate”?

3 Comments on Pontiac Solstice Build with 427 V8 Engine Swap

  1. Could I get some specifications on this Solstice? Not your parts numbers. I am not building one just writing an article for local publication on one

  2. Don, this was a build by Hot Rod Magazine and GM Performance Division, not us at CBI. Maybe try and contact them directly? Hopefully they can help. Good luck!

  3. These two links are not working…
