Bracket car, 6.0 LY6, stage 2 cam, forged pistons, 10.5-11:1 compression. Powerglide. Planning to keep it under 6500 rpm.
I have a Holley 3310 750 vacuum secondary, which is likely not the best choice.
Go to a 850 or stick with 750?
Demon, Brawler or ?
Thanks.

 

You want a mechanical secondary carb. Put that vac carb on your grandmas Caprice. Seriously though, here’s a link for a VERY high end carb built by a big shop. It’s on EBAY, but trust me here…I buy a LOT of stuff from these guys. Everything they sell is quality…used, but quality. Buy this carb. It prolly flows 1200+!

Thank you very much for that.

 

I have used a Holly three (3) BBL carbbe with a Wegner intake AND a Ford 351-C Distributor for racing.

I went with what I had, Original Mighty Demon 750 DP....I did have to jet it up a bunch, so I'm wanting to try an 850DP.

Similar motor, but unsure what "stage 2 cam" is ?

LY6, 10.8:1, 23X/24X cam on a 110LSA 106 CL .6XX lift

VS carbs for MPG....DP for ***** out.
