Tunnel ram bogs

I've got a bad bog off idle when nailing it. Tried it at 1100 and 1500 RPM and no difference. Idles at 1100 in gear. 2 x 750 1407 Edelbrocks. Stock jets and springs, accelerator pump in 3rd (top) hole, 3 inch spacers between carbs and breathers/scoop. Timing is by way of a MSD 6AL-2 programmable. 20 degree retard for start, 36 degrees full in at 1000 RPM. MSD pro-billet locked out.

Yes it is. Now if I can just get the bog out it. Really woke it up from the 2 x 450 Holleys. If I could only get some info on getting the bog out. Lot of good info here but couldn't find an answer.

It's fine but you have a problem with it...

If you think it woke it up,,, Take the tunnel ram off and put one 750 on it and see just how much it will really wake it up... Most motor's like your run it's best with one 750 on it... what does that tell you..

I had 450's on it but it ran out of steam around 4300. Now it hits 7k in a heart beat.

Looks like you have everything I would recommend (stall, locked out timing, ect).
What type of linkage? Don't say pregressive.
Have you tried a 50cc acc pump?
Do this happen from a rolling start?

Well, all this talk and no advice?? Ok, you need to figure out if its too much air, or too much gas causing the bog. You have a big space to fill. You could try bigger squirters. Was any weight removed from the rear butterflys (the ones that open with vacuum, not the throttle plates)? When you stab the throttle, it bogs, but hit the throttle a few times at that time and see if it takes off or gets worse. If it seems to kind of like it better, it may need a bigger shot of fuel. You may benefit from taking off the spacers - if you need/want the scoop height, put spacers above the carbs to raise it. Might be worth a try.
