Been having some issues getting my setup to run satisfactorily and will welcome any advice. At best, it is currently running "okay." Took a while to figure out the acceleration enrichment setting which eliminated the off idle bog, but it's surging on acceleration and cruise but not at idle, and the acceleration is mediocre. It ran like a bat out of hell with the Quadrajet carb.

I looked at the timing today and found that it was advancing to 54 degrees at 3000 rpm with the vacuum advance connected to manifold vacuum. Disconnected and plugged it and it maxed out at 36 degrees with 16 initial. Running a GM HEI distributor with a new vacuum canister. Double checked, it was not plugged into ported vacuum. Not sure what's going on there.

461 long-rod stroker in a '69 400 YB block, #45 small-valve heads, 10:1 cr. Melling SPC-5 cam, 198/208 @ 0.050, .404/.408, (I know, it needs more) 4 degrees advanced. Holley in-tank pump/sending unit. 460lb-ft at the rear wheels with the carb.

AFR at idle 13.5, 14 at cruise, 13 at wot. Fuel pressure 60 psi.
Acceleration enrichment 10.5 lb/hr.

Advice greatly appreciated.
