91 motor?

What motor comes in a 1991 S10 i know it has no power steering and no AC. My frined has one and i want to know what motor is in it. Also its not fuel injected

there are i believe 2 engines that come in that year , the 4.3l V-6 and the 2.8l V-6. mine is the 4.3 and it has power sterring and A/C. so narrowing it down tells me it might be the 2.8.

ok thanks man

maybe your friend removed the a/c and p/s or they were removed before he bought it

I'd guess in the base model it would be the 2.5 four cylinder iron duke engine. Something like 90 HP. Run forever and decent gas mileage, no powerhouse though.
