I have seen casting numbers with H3 and others with H4. Can anyone tell me the difference and what is the meaning of the 3 and 4. I am pretty sure
@6bblgt (https://forum.e-bodies.org/mlist/6bblgt_211) would know. Thanks

never noticed the "H3" VS. "H4", maybe an earlier version (does it have a VIN pad?) or a mold number ?? :dunno:
but, the paint stamped "605" is a 1969 B-body 18-spline :thinking: what's the partial VIN on it?
I got one with 133374 build sept 24 1969. Put into a 70 car
