Picked up this nice 1971 Cadillac core, not sure if it’s for 472 or a 500 ?or actually which model it was installed on?
..my real question concerns the extra secondary pull over enrichment holes, not the usual ones right above the secondary top air flaps, but these are even higher up and cross drilled to intersect with the primary pull over enrichment…it seems like it would be  spraying fuel from everywhere(LOL)…
is this correct for a 1971?   I’ll try to post a pix.

Cliff Ruggles:
Nothing to really worry about.  Post some pics if you can....

mcx:
Here is the picture

Cliff Ruggles:
Looks fine to me, that's where they are supposed to be...

quadrajam:
I can see no circumstances where there would be a negative pressure
at the entrance of those holes. No fuel is coming out. Maybe air bleeds for the primary
POE on the other side.  ??.  Irrelevant to proper operation. Maybe there to spook the
Holly guys even more. IMHO
