Would it help to put jet extenstions on? Carbs are sideways. Fuel pressure is 6 1/2 an use 4 port magna fuel. Or just maybe set the floats little higher? An thoughts?
Thanks

Not sure jet extensions will help, but you might be able to cure some of the problem with raising the floats some?

It does it on every pass just before i shift into 2nd. If it did it once or twice maybe think its a fluck. Do you think fuel pressure needs turned up too?

turn the fuel pressure up to 8 at idle. and check the bowl level

Calm down the wheelstand, I know that is not what you want to hear but it is probably the RIGHT way

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.

What fuel pump are you using and is there a air filter on the carbs ?

Magna Fuel 500

standard floats will close the needle and seat when fuel sloshes back

a voltage drop can slow you fuel pump down too

How long and high is it in the air? Maybe it is possible you are up long and high enough to uncover the front jets in carb long enough to cause and issue. Maybe some sort of modified jet extensions are in order? Have you watched the fuel pressure to see what it is doing? I know that is easier said than done while driving a car in the air but might take a peak.

Dont think its a voltage thing. Im back to 2 battires now.

Fuel pressure in high gear is around 6 61/4. But it dont now what fuel pressure is off the line?

Im going to cut 2 holes in the front of the cowl to let some air in. Its a piece of trash in high gear. Runs less MPH than it did before, but the 60' is best 1/8 mph is up some an 1/8 et is getting better. This should fell like afterburners kicking in!

Is it possible that fuel is sloshing into the carbs form the vents? I had that problem with my six pak and didn't realise it for a long time

Shawn how close are your carbs to the top of your hood scoop? I had to take my tunnel ram off because mine were to close and would shut off air flow to the carbs.

could be possible? But we didnt see any sign of fuel coming out? It fells like it starts this when the car is at its highest. But it happens so fast sometimes i forget. LOL

Im hoping the video shows signs of whats happening.

Injection will take care of it, Think what it'll look like with stacks sticking thru the hood!

I think the fuel in the carbs. is held down by gravity while the car is going up and once it starts to slow down going up the fuel will be released from the graivity and rise up in the fuel bowls and possibly slosh out thru the vents I used three peices of rubber hose and routed it to the rear of the air cleaner base, on my tunnel rams I'm going to use two vacume tees per carb and hook them onto the vents with a short piece of hose and connect the vents in line and leave the ends open on both ends. I should make one up and take a picture and post that instead of trynig to describe it in words
