i've got a 93 jimmy with a 4.3 and need to know how to figure out if i've got the 165 or 195 hp version since the vin code is the same for both.

Same Vin?????

What Vin code do you have? if it's a W you would have CPI which is the engine that was rated at 195hp if it is a Z then you have a TBI which is rated at 165hp.

I think the CPI are under rated, I have a 94 S10 Blazer with the CPI and it MOOOVES!
