Best 60's ever all 1.28s. Got the bump stops set as tight as im gunna set them. Leaves the best around 2000rpm. Sounds like an feels like its starved for fuel right before 2nd an then after i shift it takes it a little time to recover.
I have video i will show as soon as the get it to me.
had the same problem today, my car was leaving hard and pulling up the frontend causing my jets to be uncovered causing a lean condition.
i raised my floats up on both carbs a bunch with a drill bit and problem solved. got my best et ever in bad air.
dont touch your fuel psi, thats not your problem.

A set of 90% bent tubes would so the ends are at the
rear of the carb(what is the rear now)... might be
able to use a short piece of fuel hose to connect
them to the jets.... I'd do all of the jets to make
sure they are all getting fuel. This should work for
a test and if it corrects the problem then I'd make up
something that would be a little more permanent.
Also the comment of being slower in high gear...
it could be a air issue... put a air pan on first
that may knock out some of the hot air thats up in
the cowl(thats where its trying to escape to)

Shawn, you might want to try larger needle and seats on the carbs(might need to go to the alky seats for more flow

Chris..
Taking the hood off of something fast usually has a negative affect because fuel is pulled out of carb and ends up on the windshield. Not to mention what it does to the air...

They will if they are made to draw from further back in the bowl, and that was my idea, and I believe Als as well. It would take some custom work, as they would need to be flattened a little to allow for ending in the middle of the bowl instead of straight out from the jet. A little tubing, a torch, a (small!)hammer, and problem solved.
