Holley 600 Vacuum Secondary Carb Question

[Jim Doak]

I posted this over on FFCobra and thought that I'd ask over here, too:

Anybody have experience using a remanufactured carb?

I've currently got a Holley 650 double pumper on my Ford Racing 345-horse B-cammed crate engine. I'm using the 650 because it was on my old 331 stroker. The carb sits on top of an Edelbrock Performer RPM intake.

Although it runs pretty well, I've been thinking about trying a Holley 600 cfm vacuum secondary carb to see if it would be a little more "street friendly". Plus I think that the 650 with mechanical secondaries may be a little too big for my 302.

I've been looking at the new version of the model 1850 600 cfm vacuum secondary carb that Holley manufacturers. It no longer has adjustable floats like the older version did.

So any carb experts out there? Should I buy the new Holley 1850 without the adjustable floats? If not, does anybody have any experience with a remanufactured Holley 1850 with the old-style adjustable floats?

I definately want a Holley, no Edelbrock carbs for me. And I don't want a Street Avenger style carb. (I don't want or need an electric choke and don't mind having to tune an older version carb.)

If anyone has used a remanufactured carb, where did you get it and are/were you happy with it?

Thanks.
