Holley/Demon Carb stumble

Agree about it not fixing the problem, But you can see the front squirted giving up before the back. So if i was to put a 50 cc squirter Pump in, it would be the front and then a larger Squirter.

I had a 1000 cfm Themoquad i tried on my stockesh 340. ran grate if you got moving before you asked the secondary to do there job.

That's the same problem i'm having here with a Demon carb with 1.75 butterfly. This 850 Demon carb, in all reality is a 1000 cfm carb. Trying to work on a 408 that i shift at 5800 rpm just don't work.

My proform 850 is to big as well being i'm at 6600 feet elevation, and a, so called mild 408. that is just to big as well but i can work with it and will still work if i decide to race at a lower elevation.


Thanks
