Advance slot chart ?

I really have nothing to add here other then i feel your pain on the tuning of a combo like that. Mid 80's and my bud had another brand smallblock built with very similar specs, 11.7 with iron heads and a [email protected] with a tight 3800 stall. I worked the dizzy and 750 carb on and off for months and with the falling pump octane at the time got nowhere. 1k idle and neutral at stops. Tried to talk him into some thick head gaskets but no dice. Instead he brings me a tunnel ram a two 600's...lol. Oddly, the street manners were a little better, but with 8/9 degrees initial it was never gonna be a ''cruiser'' regardless.

Sorry for the long post, this just brought up fond/tough memories from years gone by.

Good luck getting it where you need to be and keep enjoying that awesome ride. :thumbsup:
