Thread: 4.3 ID #s

Tweet

i got a guy whos gonna ask around and try to get me a used 4.3 for my truck. he wants the ID numbers for the motor so where do i find them? and are they really necessary to find a 4.3? cant i just tell him i need a 262 4.3 V6?

Not for a 'project' car/engine. Most salvage yards want the infomation from the engine you are 'replacing', assuming that you are replacing a bad engine. There are 3 different versions of 4.3L.

1) Early carburated

2) Early injected

3) Lated injected (Vortec)

If you want to use a carb, get an early non-Vortec engine. I think it's pre '92 ('85-'91?). What yard are you working with?

its in a 92 FSC with TBI is that early injection?

You'll have to forgive me, but what's a FSC? Go to the Hot Rod Magazine website and look for an article called 'Three Quarter 350.
