for a cam I'd probably look at a lunati voodoo 60402, maybe a comp XE268.
intake, I'd ditch the performer for an air gap or performer RPM.
I'd swagger you're going to be low 14's maybe nipping a 13.8 or 13.9l, especially with the intake change....

IMO the little bit of gain isn't worth it. Longevity and consistancy is the name of the game for me. Being the quickest or fastest isn't what wins in bracket racing or in Pro heads up at times for that matter.

Even if you know how to tune the 750 double pumper, it will not perform to expectations. You have too much weight and not enough gear, compression or converter for the carb. A 750 vacuum or a different, smaller carb should work better in the long run. Nothing wrong with a 904 in a performance application if it's built right.

yes, the eddie will be a better fit. I had a stock long block 360, 1406 eddie, Air gap, comp XE262, MP166K converter and 3.55's, and 27" tires and my 5th ave could keep up with a stock 5.7L LX car, which means it should have been a low 14, maybe nipping the 13's car (never had it to the track)
FWIW, on that eddie, I used the stock secondary jets in the primary, stepped the cruise needles down one size, and went with .089" secondary jets to get my mixture right using a friends LM1 Wideband 02 sensor.

I also have a 600 edlebrock on the shelf...Would that be a better carb??? Would i be better off trying to find some steper gears?? I know where i can find suregrips that have 4:10s and one with 4:30s but i wasnt sure if that steep of gear would help??
The 72 340 swinger I had came w/ a 625 Carter, can ran a best of 14.02. I put on a 750HP and the car went 13.80. which do you think is a better carb? and you have more cubes and more cam.

The 750 DP is one of the best carbs ever made. with a 3000 stall just try it. A 600 is probably too small for all out peformance but you can try it? don't over think anything till you drive and make some runs. Big first items is make sure you have your distributor re curved with light springs right from the get go.Set total mechanical advance to 35 or 36 and don't hook up vacuum advance for a couple three weeks (if ever it's a crude cruise gas mileage device designed in a time we had way different fuels than now) If you must try the vacuum advance make sure it is on ported vacuum and not manifold it SHOULD NOT affect idle when you plug or unplug it. Have some fun
