660 Holley #4224 opinion?

[SCOBRAC]

Hmmm... I feared this might be the case. Maybe I will look into rejetting and reworking the secondary system in the 600's. The last 1850 I had was on a 1.2 liter rotary engine. (I only rail about being over carburated I didn't say I never did it) I just hated that carb. Not for what it was, but what I needed to do to it to make it work. It worked really well after a ton of trial and error. I got almost 150 hp per liter out of that 12a rotary. Now every time I see an 1850 I think about it. It was still a 188 hp 2400 pound car, that was double the factory HP.

I actually have already bought a pair of these carbs from a racer who ran them on an FE and had them reworked for road racing, air horns milled, rejetted etc. I was a little leary of the 50cc (x2) accelerator pumps going off at once. Who knows maybe I can make them work with 30cc pumps to get the thing to be more managable off idle. Probably not.

I got them thinking the WOT would be impressive and it will be I'm sure. He's got 76 jets in them now and that seems really large. I was thinking 68's too. I'm wondering whether your flooding during cornering and braking isn't due to the fuel level being a bit high. Thats a common problem with road racing carbs. There are baffles that you can install in the bowls to stop it if lowering the fuel level creates a starvation problem.

I too was inspired to buy these for the bad boy factor. I wish Holley would produce more carbs without choke assemblies, these don't have chokes but the hir horns being milled off really sealed the deal.

They are expensive new almost $600 each. I got this reworked pair, freshly rebuilt, refinished etc. inc. shipping for $485.
