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.
The difference in horsepower between stock heads and Vortec heads on a 350 Chevy can vary, but typically, upgrading to Vortec heads can yield an increase of around 30 to 50 horsepower. Vortec heads are designed for better airflow and combustion efficiency, which contributes to this gain. The actual increase can depend on the overall engine setup and tuning.
For an '84 Silverado, a 350 Vortec engine would generally be a better choice compared to the 305 with a 488 cam. The 350 Vortec offers more displacement, which translates to greater torque and horsepower potential, making it more suitable for various driving conditions. Additionally, the Vortec heads provide improved airflow and efficiency, enhancing overall performance. If you're looking for a balance of power and reliability, the 350 Vortec is likely the superior option.
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
The primary difference between the 350 V8 Vortec and the 305 V8 Vortec Chevy engines lies in their displacement and power output. The 350 V8 has a larger displacement of 5.7 liters, typically producing more horsepower and torque compared to the 305 V8, which has a displacement of 5.0 liters. Additionally, the 350 Vortec often features enhanced performance characteristics, making it a popular choice for applications requiring more power, such as towing or performance vehicles. Both engines use the Vortec design, which incorporates advanced cylinder head technology for improved airflow and efficiency.
