Sorry guys, I know that this is problaly one of the basics ask to do, but I just bought a 1988 350 TBI that came out from a 2wd Suburban, and I was wondering about the HP's and Torque. The engine is in stock form

Thanks

 

I think in 88, they are around 210hp and 300tq.

A good upgrade would be putting in a roller cam and lifters, you're block is already machined for them and you'll see big increases over a flat tappet setup and the fact the cam you will pick will be bigger.
