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.
There are 4 different Vortec engines for that year. Stock horsepower at the crank are: The 4.3L (262ci) Vortec V6 has 190hp The 5.0L (305ci) Vortec V8 has 230hp The 5.7L (350ci) Vortec V8 has 255hp The 7.4L (454ci) Vortec V8 has 290hp
175 hp 205 ft lbs of torque
they should but rem vortechs r fuel injected and most 350s rnt.
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.
Most major auto part stores will stock the standard EGR valve for a Vortec 4.3-liter engine. You may have to visit several to find one that has it.
197 rwh stock
190hp
The 8.1L vortec comes stock with 330 hp and about 450 pound feet of torque.
