1989 s10 blazer 350 swap
 

Hi i need help, i have a 1989 s10 blazer 4.3 v6 and i have a 350 to swap in but not sure what all i will have to do to put it in and what can stay stock and what can't, anything will help

Hmmm - changes:

- Engine mounts?
- Electrical wiring engine bay
- Oil pan if it is a 4x4 may get in the way.
- Fan to radiator setup or fan has to go - electrical fans (due space in front)
- Injection? What does the 350 have? TBI? Carb?
- Ignition? HEI? standalone?
- Sensors and feed to the ECU (gauges etc.) or ECU from 350?
- Exhaust may work but might need some modifications
- Coolant hoses (water)

Principal questions:
What is the actual setup of the V6? (1989 most probably TBI injection.)
What is the actual setup of the V8? Year, type, TBI, carb, MPFI?
