Generally the 4.3L puts out around 180-190hp at 4400 rpm and 245-260 ft/lbs at 2600 rpm. My 97' on a dyno was 161hp and 218ft/lbs and with a 18% drivetrain loss is 189 and 257.
207 horsepower with 235 lbs of torque ;P right on the money
330
190 hp
no, 1998 is a year of its own, you will need a 98 trans
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.
367hp
Will a 2000 blazer transmission fit a 1998 s 10 chevy 4x4 truck
250HP
Factory rating was 230 H.P.
The axle nut torque specifications for a 1998 Chevy 4x4 are 165 lb ft. The metric specs are 225 N m.
Yes as long as the 99 is the OLD body style.
When the roads are slippery
