Quote: ...Indy low deck tunnel ram for my 511" 400 based stroker... I am going to run two annular 1050 CFM QuickFuel 4150 carbs
If it were me...Those QF 1050 cfm 4150's will flow more than the older style 1050 Holleys. I would just put a pair of annular 750's IF YOU MUST run 4150's. Or just a set of the older 4500's. There is a guy on here occasionally (MONTESSA) that runs 440-1's on a 572" he was making pretty near 950 HP with 2 750 4150's.
I am going to follow your advice there and test with some 650's and 750's on the dyno. If I didn't already have one 1050 that is running on the car and one that fell in my lap I'd skip the idea altogether. I'd hate to have parts laying around and not try them. My QF 1050-AN runs so nice on the street I'd hate to let it go.
If I could find a set of affordable aluminum 4500 series carbs I'd give it a shot but so far nothing has surfaced. Long ago I made a vow to never own a pot metal carb again for a wide array of reasons.
