What kind of power will I make if I take a stock 350 tbi shortblock and added cast iron vortec heads (1.95 valves with 175cc intake runners) and the aluminum vortec intake manifolds with a proper tune?
Also if I added a nice cam what would the results be?

 

Probably in the 230-250 fwhp range depending on exact parts used. Adding a bigger cam/ headers/exhaust depending on parts used can get you up to a little over 400 fwhp, then the vortecs start running out of air.

 

hey how did you tune your setup?

 

Pretty much following the suggestion you see in some of the stickies above. Was not to bad to get it to run, but took a lot of time to fine tune it. Still occassionally notice things and make changes.
