Hey guys,

This is my first post on the forum. I have a 65 chevelle with a 327 I run E85 on with a 750 DP carb w/o choke. I have had to make some mods to get this thing right (and still isn't right), and I am having a terrible time with a lean bog right now.
It's also FLAT/doesn't build power on the upper rpm range.

I have an AFR that I just installed.

My motor is built pretty solid with a cam with a little overlap, decked block, shaved/ported heads, about 12.5-13-1 compression, 4.10 rear th400 with shift kit. If you need more info on any of this let me know.

My initial set up from Rob was:

Air bleeds: 31/68
PVCR: .067
Jets: 89/99 (rear has extensions)
PV:4.5 front (rear is blocked)
IFR: .041
Boosters: 157 ( maybe a little small)
accel pump(s): 30 cc
squirters: 45 (I have tried 42's without luck)

Can't get the thing to idle without the following changes and I have to go in more than 3/4 turn on the 4 corner idle which gives me about .9 lambda and 13 inches of vacuum. I made the following changes, but left everything else the same:

Air bleeds: 31/67
Jets: 83/94
IFR: .035

Any of you guys running a similar sbc combo on E85 that have had luck with your settings, or does anyone have any advice? Thanks
