1991 suburban 350 keep?

[rjohn]

Just wanna get people's opinions on the original 5.7 tbi shes got 180km runs smooth, for sitting 12 years.i was initially goin to put a 400 small block in but she runs to good. So iam gonna keep this tbi, just clean her up.just wondering if I can even get this old 5.7 to spin the rears lol. shes a gutless motor I have a stock tbi in my daily 94 she sounds like your goin fast but doesnt spin tires. I just want this square to have a bit of power, the previous owner said the head gaskets went so when the shop redid them they installed vortec heads I have no ideas how to check this, but it sounds like a forward step in performance from what I hear.

I’d keep the tbi personally. From someone who has all styles of square bodies. The suburban is last one I feel the need to do burnouts with. They’re so big and bulky that I don’t even try to corner carve or throw it around at all. Don’t get me wrong, it needs to get out of its own way and merge on the highway decently, but that’s about it for me.

take the tbi motor and tune it up and enjoy it for what it is. You start swapping motors, Swap to carburetor and things will just not work together as nicely.

you can tell if it has vortec heads by looking at the intake manifold to head bolts. If they are vertical, it’s got vortec heads. If they go in on an angle, they’re the regular tbi heads.
