Re: Whats the stock HP??

didnt read the whole thing, the year was right in front of me . blazes is right:
2wd s-series = 180hp/245 tq
4wd s-series = 190hp/250 tq
only difference between the two is the computer's tuning

Re: Whats the stock HP??

I've been looking for two days to figure this out. I am buying a 94 s10 4.3 where the 8th digit is a W. I can't seem to find a definitive answer whether the W is the higher HP or the Z is. Can anyone shed some light on this? Thanks.

94 CPI engine code "W" was the high performance version of the 4.3L
200hp, 250lbs torque

I have to look for the "Z" engine numbers, as I don't remember them, but it was the TBI 4.3 which had lower HP and Torque.

Re: Whats the stock HP??

Hey Thanks!!
I'm feeling better and better about this purchase! It only has 71k on it and is spotless. Only a little rust on the bottom of the drivers door. This is my new plow truck/utility truck (my 91s10 blazer bit the dust).

I appreciate your help!
