depends on the year. This involves a little bit of reading but your answer is in it and a whole lot more lol http://en.wikipedia.org/wiki/Chevrolet_C/K
190hp
That engines in 1996+ 1500 pickups are rated at 195 horse power. In earlier years it was less but do not recall the number. I believe the first year to be 195 was 1996. 1993-95 had 160 hp vortec
none!!!!!!!!!!
4.3 liter
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.
no
A 1993 Chevy does not have a carburetor, it is fuel injected.
The tire size should be P235-75R -15. I have a 1998 Chevy Cheyenne 1500 4x4. Tire size is 265-75R-16
The 5.7 Liter Hemi had 345 Horsepower in 2007 & 2008 - went up to 390 horsepower in 2009
Factory rating is 200 horsepower.
