Robert’s frame off restoration was an awesome one to get to be a part of. I mean everybody loves a nice square body.

We helped him out with some internal engine work, Holley Terminator X install
Dual tank fuel system that works just as factory, keeping them switchable with the flip of a switch,
Hot and cold side turbo kit,
Lots of odds and ends to get this one up and running. Robert will be finishing up his end and sending it back over for us to finish the exhaust and get it tuned up on the dyno.

Dyno Day

There's nothing quite like watching the numbers climb on the dyno.

The anticipation. The sound. The results.

Another awesome one out the door! This car came to us with a hurt lifter.
The shop ended up purchasing this hot rod and completely going through it before one of our good buddies ended up buying it.
Thanks to Broc at Shaker Inc. for doing the machine work on the short block and our team here at FSI for the meticulous reassembly and addressing every issue this car had.
On only 9 Psi of boost it laid down a healthy 757 RWHP and is just a blast to drive with the Circle D converter keeping it in the power band!
