The new ones that he sells are not OEM Motorcrafts...they are an aftermarket clone with Ford internals. On the housing, there should be an embossed stamp showing the venturi size, etc.. and the one I got does not have any of that on it..
Here is a reply from him regarding a question pointed towards that subject:
These are aftermarket brand new. OEM ford carbs haven't been made since the late 80's. They are pretty good and I replace all internals w/ quality Walker parts (power valve, jets, accel pump, gaskets, etc. The ones I build for $280 are all original Ford parts.
It only hurts while you're breathing..
