First off, what's the factory hp/torque numbers for a '97 Vortec 350? Next what kind of parts can be added to boost the hp for a relatively low cost? Also, what will it take to get 400hp? and 450 or so ft.lbs. of torque?

Around 255hp I believe it was...

Tune, intake, catback, underdrive pulleys, e-fans, are all good places to start on the cheap.

400hp at the crank will need a cam, probably better heads, Marine intake for more injector, headers, e-fans, etc. Basically all bolt ons.

Once you add up the cost of all of the parts you would need to get that kind of power out of your vortec 350, you could just by a LQ4 6.0L and swap it in:rocking: . Then your power capabilities are pretty much endless.

1996-02 Vortec 350 L31
255 [email protected] rpm 330 lb/ft torque at 2800 rpm

383 cubic inches, ported Vortec Iron heads, headers, GM LT4 Hotcam 218°/228° duration at 0.050" will net you roughly 330rwhp and 380 rwtq or roughly 395 hp and 455 lb/ft torque at teh crank.

This combo with a 2800 rpm Precision Industries 2800 rpm 9.5" torque converter ran a 14.1 in teh 1/4 mile in a full weight extended cab 2wd truck. LT4 knock module, V Maxx intake manifold spacer and new plugs put this truck in teh 13's with a 13.7 in the 1/4 mile.
