First post here, please bare with me !

So I built one of the 7 engines in the article "7 Hot Engine Combos - Mild to Wild" from Chevy High Performance magazine August 2003, I think it was the Muzak Mouse but I do not recall, specs of my build are as follows:
-350 SBC, 4 bolt mains, 9:1 compression
-Cam is an SSI from PAW: 214/224 duration (280/290 adv) with .443/.465 lift @50
-GM Cast Iron Vortec Heads
-Edelbrock Performer RPM Air Gap Intake
-GM Ram's Horns manifolds, 2-1/2" (clearance issue or I would have gone with headers)
-600 CFM Carb (mine is a Carter AFB)

Engine runs GREAT! It is in my '59 Chevy 1/2 Ton pickup with a Turbo350 trans and a 10 bolt corporate wtih 3.42 gears. I believe my torque converter stall is around 2100-2400 but the trans was a freebie so I didn't ask too many questions at the time!

Part throttle and WOT performance are awesome but transitioning from idle to the primary circuit is an issue. I have called and worked with Edelbrock Tech Support but alas, no avail.

Engine has 18 in of vacuum idling in park between 800-850 RPM and drops to 600-650 RPM in gear, not too much lope either; it takes off smooth with minimal throttle. Distributor is stock HEI with 20 degree weights and stock springs, for now, vacuum hose disconnected, for now (possibly forever), I am all in with 36 degrees of advance around 2800 RPM (16 degrees initial timing).

PROBLEM is, truck cannot get off the line... It bogs or stalls if you floor it.

I would appreciate any insight or advice from the experts out there or anyone that has a similar build; I know this combo will work, I just have not coaxed the genie out of the bottle yet. Thanks in advance
