Check the RPO codes in the glove box!

So which is the better engine?

LB1 85 86 ENGINE, 4.3L V6 (4.3N)
LB4 85 86 ENGINE, 4.3L V6 (4.3Z)

I have the LB4 85 86 ENGINE, 4.3L V6 (4.3Z)

Oh and also I have the GU6 76 88 AXLE,RR 3.42 RATIO

If I'm not mistaken, I think thats the 195hp CPI motor:uhoh: :thumbup:

should be a quick little truck with that gearing and a 5 speed!

Sorry buy you are mistaken. The CPI was used '92-95 and is an L35 model with "W" VIN. It is the direct predecessor to your newer L35 "W" CSFI.
