Between 370 and 390
Type your answer here... 255 horsepower and 335 lbs of torque
It has 275 hp.
The Vortec 5.3 Liter V8 engine produces 295 horse power.
Well , the 1.3 liter ( 81 cubic inch ) engine in a 1991 Ford Festiva is rated at 63 horsepower
230, it went to 255 in 1996 with the vortec
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.
2001 and up produced 270-285hp with 285-295ft-lbs torque.
A GM Vortec 305 4.8 liter engine has a rating of 315 horsepower. It is not good for towing, however, having little torque on the low end.
I believe it is 260 horsepower.
It depends on the year of the vortec. From what I see the 05 is pushing 285hp
The horsepower of a GMC Sierra is 355 hp.
I believe 190 hp. That's what my 99 Jimmy with a vortec 4.3 is estimated at. The basic 4.3 Vortec V-6 was rated at 160 or 165 hp. Starting in 1994 an "enhanced Vortec" 4.3 V-6 of 195 HP became available alongside the basic version.
