About 290 hp.
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.
YES they will bolt right in.
Yes
Contrary to what people think,A 1994 Extended Cab Chevy Sportside Silverado came with the 5.7-liter 210-hp V8.
