What engine do I have in my S10 converion ratrod
My son Bought a rat rod with a 1950 Chevy pickup body and an S10 frame and running gear. It has a leaking freeze plug. It is a V6 but we don't know the year or the size. It is probably pre 1990 or so. The engine valve covers do not say vortex and the air cleaner in a conventional circle as I used to have on my mid 60's chevys. what are the key changes in V6's and how do I spot them?
Is there a TBI on there or a carb? Never the less it may be a 4.3L engine. If you can find some block numbers I can look it up.
It has a carb and fan belts (not serpentine)
