For Magic Mike: my 250 is .030 overbore with stock type pistons and carefully clearanced and balanced. The head has had the bolt bosses removed but no lumps installed, fully ported and has a 1.94 / 1.50 valve set up. It is also milled .080". Running a 214 @.050" Comp Cam with Crane Gold roller rockers. Clifford street rod tubular headers with 2 inch pipes into short stock type mufflers to keep the sharp exhaust crack noise bearable. Running a Chevy HEI coil in cap distrib but it has all the innards and the coil replaced with MSD items. R44XLS plugs gapped at .045" and Taylor Spiro Pro wires.
Right now I don't have the jet and rod numbers in front of me but I'll post them tomorrow for you.
I first ran this 500 carb on a 305 V thingy and found it to be too rich out of the box for the 305 which has a similar mild cam and full dual exhaust so a quick guess would be thats why it is too rich for your 292. In fact we ran it for a while on my sons 350 Chevy V8 that has a 224 duration cam and it still needed a minor rod change. They take a little time and patience to tune and after installing 5 or 6 in different sizes on various engines I can tell you that I haven't installed one yet that was a perfect set up right out of the box. No universal carb is.
