carb question
Everybody says oh a 300 runs just fine with a Holley 600, a intake and headers on it, correct?
Well why can't I ever get a decent afr?
I'm at the point where I'm gonna either swap carbs to a 465-530 range, or throw money at someone to play with my metering blocks.
I've got a built motor and I can't get it to suck enough air for the life of me at idle.
I've git a quick fuel 600. I've gone from 70s on the idle air bleeds to 76s and have barely made a difference. Maybe my 6.5 psi is too much fuel? I know that's an issue with edelbroks but Holley too?

Which intake manifold do you have? C series, Dual port, or Clifford? That might make a difference if you are using a c series. I was told a dual port can better utilize a big carb because of its runners are designed to be higher velocity.
However, It sounds like something simpler is going on. Hard to tell from over here in the Central Valley of California though.

The DP is rated around 390 - 500cfm
The C and Clifford are 500+ cfm.
The QuickFuel carb is about one of, if not thee, most tuneable carbs in stock form that you can buy. If you can't get it to lean out or meter where you want it to, it's either something isn't set right, or there's a defect with the carb and you have unmetered fuel entering into the system when it shouldn't be.

That's what I'm thinking. I don't know how to tune metering blocks, and I need to swap my lifters so I think I'll have my friend get a chance to play with a quick fuel and do all of that. I don't want to **** up my lifters and rollers since I've never done that before but I'd gladly help someone do it so I can learn.
Also, I'm going to buy the 625 street demon and run it and see how it is! Worse case scenario I get my money back?
