Manifold suggestions

Now that I am about finished with the suspension upgrade to my 67. I am thinking about throwing some more dollars at the motor. I want to switch to MSD ignition, add an exhaust crossover, and upgrade my intake and carb. I am thinking an 800 double-pumper Holley but am not sure about manifold.

Currently: Edlebrock Performer (mainly for hood clearance issues), 750cfm vacuum Holley (3310), 429ci bored .030, ported/polished heads, heads and block are decked .001, compression is 12:1, cam specs are solid lifter, .588 lift, 286 duration. 1500 stall (this keeps it very streetable and the cops off of me, since they have had their eye on me since high school.) Redline 6500-7000, dyno'd @ 372rwhp/490ft-lbs.

Any suggestions for manifold and carb??

for budget considerations, keep the carb and upgrade the intake to performer rpm or victor jr (depending on how high you want to rev). With new carb... 750 Demon and Vic Jr.

Both would net major power.

edit: only change to Vic Jr if you up your stall converter some.
