I have a combo in mind that I think should work very well. Here it is, let me know what you think.

Holley 750 double pumper carb
AFR 190cc street heads
AFR FloPower RPM intake
Comp Cams 280° Magnum hydraulic
280° of duration
230° of duration @ 0.050 in. lift
0.480 in. lift
1 3/4 headers
MSD distributor
9.5:1

Thanks

I have not used that intake.
I would say you are right on the edge for going to a single plane intake like a Victor intake.
To cross over to the 500 hp area.
I would run a hyd. roller cam.
I would try a Comp. cam XR288HR or a Crane part number 118571.
With those heads and either one of the cams listed above I would try and run 10.5 to 1 comp. ratio.
If you can't run that much comp. ratio take about five degree's of duration off the cam at .050.
Yes the engine will run on 92 pump gas and about 36 degree's total timing.
