wich do yall prefer

Well, I've always been partial to British Zenith updrafts myself ... NOT!

Seriously ... ASSUMING that you mean the "usual" 4-BBL aftermarket carbs ... I like Holleys.

There are a ton of them out there, parts are plentiful, and they are relatively simple to disassemble / re-assemble. I'd recommend one that has the dual inlet center-pivot float bowls, because the single-inlet with a transfer-tube style causes most folks a lot of stress.

On the other hand, though, most mechanics that I talk to seem to prefer Carter AVS or AFB carbs. I am considering one of Edelbrock's Thunder AVS (Carter Style) for my current project (Chevy 454 in a 1966 GMC).

I scares me a little to see that these are being built by Magnetti Macaroni though. They were the guys that built some really odd-ball alternators on agricultural equipment, and I used to shudder a little every time some old farmer brought one in for testing / repair!

The Holley model 4010 hands down. I'd take mine over a BG or 4150 any day.

As far as performance goes I'll put a Demon up against anything.

Nothing beats the Tillotson!

I have ran just about every kind of carb and the easiest I ever have had to tune was a Demon. They all extremely close out of the box but you do pay for this. The Holleys are good but require a lot more tuning which in the long run come very close to costing what you pay for a Demon when you figure in the parts and your time.

I recommend that all the competition use a holley 1850.

I like the Holley carbs, easy to tune. I'm on my second Holley now a 750 double pumper. Had a 650 Vacuum secondary on my old 69 Chevelle
