The motor is really fairly old and basic as far as the computer goes. It's the post '86 TBI 350. Good solid engine that will respond to the typical "old school" mods. Unless you're really willing to spend on new parts such as cam, exhaust intake, etc, I'd just leave it.

The vortec injection system is junk IMO. Worse than TBI even lol. Ditch the stock dinky head pipes and cats.... Tuning is limited because of the controller. You can do the 0411 pcm swap to make it truly tunable if you want... or contact someone with the tunercat software to do the existing one. So no.... not Blackbear lol.
