3.2 SS engine and carb set-up reference list

I realized after reading a thread by Mazing3, that there are a lot of us with 3.2 SS that are yet to see the best performance out of our engines. Its with that in mind that I thought a thread where you could post your engine build with the carb settings, and possibly the dyno stats and your impression of how it is running could be invaluable. Especially to someone with a fresh build to give them a starting point for there carbs.

Mine is with JE pistons 9.5, Mahle cyl. ARP rod and head bolts, heads intakes ported to 39mm with heavier springs, single plug, MSD 6AL digital, SSI.
46 PMO
36 vents
145 mains
55 idles
130 idle airs
190 airs
F 11 emul. tubes

This is the set up I got from PMO.
The engine dyno at 226 on a Mustang dyno. I changed the mains to 155 and saw a big jump in power, but have yet to make another visit to the dyno. I feel that there is still more to be had and in the spring I am going to increase the main size some more and the airs to 180.

Nice Thread! I have a freshly rebuilt standard 3.2 with 46mm PMO's. 9.5:1 JE pistons, 1 5/8" headers and DC40 Cams. I have an AFR Gauge and have gone thru a few jets. I am currently running-

-38mm vents
-160 mains (give 12.8-13.4 afr wot max, @68f air temp) , (170 mains give 12.0-12.6 afr WOT)
-190 air
-F11 Tubes
-55 idle

Currently I can balance the idle to be 14.5, but as soon as I give it a small amount of throttle I'm at 12:1 afr, so that's about what I cruise at. Funny thing is larger amounts of throttle it leans out under 3k rpm. Overall it does run pretty well. I want to try different emulsion tubes to see if I can lean out the cruise afr, I might also look at my idle air correctors.
