Small Block & Big Block Chevy Specific - Center Squirt Carbs

I'm curious, does anybody have any experience with 660 Holley (center squirt, annular booster) carbs on tunnel rams? We're looking at putting a pair on dad's '69 Camaro (427, big ports, 2.30" I, not sure of exhaust, 12.5:1 compression - closed chamber, .747"/.737" lift and 289*/279* duration @ .050" lift solid roller cam, wound to 8,000 RPM). Who thinks what?

Tunnel rams are cool. Those 660's will probably work well.

Personally I would put 1 Dominator on a nice single plane intake :hail:

i second that

I dunno much about those carbs,but 2 750 quick fuels would work nicely assuming you got a decent cam under ya

the center squirt holleys (4224) work OK but unless you have the metering block kits with the changable rear jets they are fairly useless on a race car, plus the single feed makes changing jets even a bigger pain. I used them on a lot of cars over the years but with that size cam you have I would use a good late model intake with a pair annular discharge 4 corner idle 750-850s.

I have ran a pair of 1050s on setups less radical then what you have there with good results - on a race car. Two 660s on a tunnel ram doesnt = a 1320 on a single carb intake, you can pretty much run two of the same size carbs you can run on a single 4bbl intake. A GOOD tunnel ram is always worth power over a single 4bbl - just is a hassle with linkage, fuel lines, idle and paying double for carbs etc :)
