This is my 79 TA - it has 230,000 mile on the original 403 Olds motor and its turbo 350 trans. I've added performance parts to both the engine and trans but the heads have never been off the block and trans has never been rebuilt. It does have edelbrock performer cam and intake, Dynomax headers, dual Exhaust, shift kit in the trans, 3.42:1 rear gear, welded sub-frame connections, and an electric black-max fan. Plus Re-tuned Q-jet carb

77 Trans Am Special Edition - Rare 403 Engine Auto - Cam Break-in
This is Demp's 77 Trans Am that we are just about ready to finish up within the next couple weeks for him. Gary and Dylan started it today for the first time since we started on it last summer for him. Breaking in the Cam and making sure all is good with the engine. Finishing a complete Frame-Off restoration. It is a Rare 77 TA, with the Special Edition Package, and was one of the few 6.6 Liter cars of that year to get a 403 Olds Engine.

Ressurection of the '72 Cutlass Supreme
From wrecked basket case to not-quite-so-much-of-a-basket case. Sorry, no burnout on this one (not really sure why I didn't then, this vid's like 4 or 5 years old... You might wanna stay close to the volume control just in case, however :-) Under the hood is a '77 Olds 403, Comp Cams 280 Magnum, Offy dual-port intake and (IIRC) Blackjack AKC headers, Qjet and GM HEI, TH350, and I'm not sure what gears are in it - open diff, has not seen the street yet.
