Wow does that look familiar! Brings back many thoughts of the '66 GTO we built a couple years ago.
Thanks for posting, Ken. Cool story, and a cool car. When you get a chance, post up your plans for the car. We'll all be interested to follow along!
Sorry I have not done this sooner:
The plan is a Pro Touring style daily driver that can double for drag or road course duty for fun. How I am planning to do this is as follows:
Chassis - Boxed frame and gussets for both top and bottom rear trailing arm brackets. Sandblasted and powdercoated.
Suspension - Air Ride system using Select Series Shockwaves w/ internal height sensors - that way I can go from a nice Caddy ride to carving corners at the touch of a button. The system will include Strong Arms, Sway Bars, Tall Spindles and a 5 gallon E3 AirPod.
Four wheel disks brakes - More than likely a C5/C6 package.
Rear End - Car 12 Bolt factory Eaton Posi, new custom thick axles, 1350 yoke and powder coated.
Transmission - 4L80E built to the hilt inside but with the factory style shift firmness and the computer programed for the Tow/Haul to be a performance tune.
Engine - GMPP LS376/480 Crate. I am still undecided about whose motor mount swap brackets and exhaust to use. I am concerned with clearence issues if I use full length headers. Will see what happens when I mock it all up.
Interior - The only firm ideas for the interior is to use late model GTO seats preferably both front and back and a Vintage Air system.
Body - Color(s) yet to be decided. I will probably be driving it ugly for a while awaiting more $$$$$.
Will add details as the build goes along.
