i have a 1998 Z71 and i recently put a K&n cold air intake which helped a lil. I would put a set of headers on it. If ur wanting to do all the work on the outside of the motor then i would go with (programmer, intake, exhaust-true duals, throttle body spacer. performance wires and plugs, performance cap and rotor. the headers and intake should wake it up. i have headers on my truck that run down to 2 1/4 inch straights pipes that are dual all the way back. i cut my cats off and welded a peice of pipe up there and i noticed a really big difference when i did that. now if ur looking for internal parts which are very expensive, i would put a stage 2 or 3 cam( which ever one duznt mess up your computer. (roller rockers and a nice cam would wake it up pretty good). but if your like me an dnt want to spend the money or time then i would get exhaust, intake, programmer, headers, throttlebody spacer. and if you have a truck older than a 1998 i would get a performance throtttle body to get that gas flowin good.
I believe it is 260 horsepower.
Every vehicle has a different type of horsepower depending on the specifications of the vehicle. The 1999 Tahoe Z71 350 Vortec Engine has a horsepower of 255 at 4600 RPMs.
It has 255 horsepower bone stock
245 hp.
Probably about 240 or close. Move to a 96 and it's a lot more. The Vortec started in 96 with the 350 (5.7) and 454 (7.4). I understand the Vortec 5.7 had a little more power than the non-Vortec 7.4, and the Vortec 5.7 has 250 horsepower.
255 HP from the factory.
250-290 hp
Try a search for vortec engines
in 95 they went to the vortec engine but a 94 (like mine) had 200hp and 300 ft/lbs torque from the factory
Free flowing exhaust, nitrous
I own a 93 Chevy Silverado K1500 4x4 with V8 350 TBI 5.7L. so unless Chevy has changed their blocks, i would suggest that naturally your block is a SB 350. However, since your question was about horsepower, not which block you have, I will tell you the horsepower. The 1998 Vortec 5.7 liter makes 255 horsepower.
how do you set valve on 1998 350 vortec
