Congrats!
Whats the list # of the 390 Holley and does it have metering blocks on primary and secondary or just a metering plate in the back?

Yup I've run a bone stock 292, Offy or Clifford intake, 390 Holley but all stock otherwise, runs great. The engine only "wants" about 300cfm so the secondary only opens maybe 1/2 or 2/3 of the way.

Mine is a 6390 Holley, I run 52 Jets pri and sec, the pri PVCR is .028 and the sec PVCR is .031, runs good that way so it just depends on what carb details are.

I think the List 6299 is the "Pinto/Vega" version set up for 4cyl so you might have to fiddle if you have that one.

It makes a big diff on the top end, the 292 wont starve any more.

$200 to upgrade the bowls????!!
Well, those side hung bowls were good enough for the 427 Ford and the 327 L76 and L79 so they should be good enough for a 292!
I'd save the #200 for that doggone expensive intake!
