350 tbi options

[Bdub76]

Bought a 94 GMC sierra 1500. Truck originally was a 305 auto(4L). Someone put a 350/th350 in it. Block code came up a 86 & up. Could be 2 or 4 bolt main? Haven’t pulled pan to check. Anyways, it’s a tbi set up. Stock headers. Stock intake. Just looking for the best bang for my buck performance wise. Looking to give the truck a little more of its true potential. Is it as simple as headers, cam, and maybe a better chip for the tbi?

Start by looking up upgrades to the ignition system. A strong spark actually helps these a lot. Then an intake with a mild cam never hurts. Yes a chip/tune will be needed, but overall should make a solid runner.

You can still get custom tune chips made.

So you don’t think headers are important?

You got any recommendations for any of them?

I’ve read about a lot of problems. Or atleast alot of trial & error. Just looking to see if I should invest in the tbi set up or switch to carb or even something like the aces Efi stuff.

Aces efi is crap. If you want more power put a ls in it.
