s 10 vrs. blazer

does my blazer have the same exact engin as the s 10?

they are both 4.3 L (i think), if so could i buy perfomance parts for an s 10 to fit the blazer?

i take it no onw knows...

Well yes they should be the same motor. I am not sure if the s-10 came with two different versions of the 4.3 but in the blazers they came with either a standard 4.3 with throttle body injection or a 4.3 with central port fuel injection. The difference being more horsepower and more ft. lbs of tourqe on the central port fuel injection. Hopefully that helps. Oh yeah and the air filtration system is different on both as well.

crap, that makes everything complicated.
