81 NASCAR Turbo Trans Am
81 Turbo Trans Am NASCAR addition LS3 Swap Holley Terminator X Max 550-918
i bought my Trans Am back in 1985... I drove it for about 6 years... drove the brakes into the ground... as a teen, I couldn’t really afford to repair the car at the time. I ended up storing it in my parents garage.... where it sat for over 33 years. I decided to pull it out in the fall of 2019. After repairs to the braking system... I had to pull the engine due to a bad oil leak... rear cam seal ... I decided to do a LS swap after anticipating I may need to rebuild a 200 hp engine .... I decided a LS3 and 4 speed automatic would be a nice replacement.... almost 3 times the horse power and 200LB lighter in weight .
this is what I’ve done so far.
