OK, I give up. Help me pick out a new carb for my combo.

OK Guys, I'm having a helluva time choosing a carb, and I don't seem to get anyone serious on the phone when I call around.

Here's what I've got now:

5.9 Magnum stock shortblock.
Iron Ram (EQ) Magnum heads
RPM Air Gap intake
1-5/8 headers, 2.5" exhaust with mufflers.
Transbrake 904, with 3800 stall.
4.11 gear (switching to 3.91 as I don't have )

Car weighs 3270 with me in it.

Currently has a 670 Street avenger vacuum secondary on it. I want to put on a double pumper.

Max RPM with the 670 is about 6300. Car typically runs best shifted at 5700 RPM.

Car has run a weather assisted best of 11.79 @ 111, but had to let off shortly before the trap as I've got too much gear. It 60s at around 1.6 consistently, but car goes, then bogs slightly on launch. I'm pretty tired of trying to tune the secondaries to eliminate the bog.

I'm thinking a 750 double pumper would be a good choice, but all the
calculators show 650 to be more optimal. I'm not hung up on numbers but don't want to miss out on power or buy twice.

Anyone have any recommendations based on a similar combination? I would like to keep it somehwat streetable, but it doesn't necessarily have to have a choke.

Thanks for any help!

Steve
