I guess that a carb would have to be a 'name' brand. I've purchased quite a few car items that have the Summit brand, but am always suspicious as to what quality controls are used on items like carbs and ignitions.

Those Quick Fuel carbs - had heard of them, just hadn't looked at their web site. They seem to cover about everything for a performance carb

One more comment about Summit. Lately I've been spending more time looking for other sources for parts. In prep for opening my Ford engine, I went looking for a one piece pan gasket for the early pan I'll be installing, head, intake and timing housing gaskets. I ended up sourcing them from Rock Auto Parts. The dollar savings were more then just a couple bucks - like almost 50% on just the pan and about 35% on the head gaskets plus shipping was at cost, not the Summit formerly "free shipping", but now a graduated scale. Yeah, I still like Summit, but not quite as well any more:

"Delivery and handling on all orders is non- refundable and based on your order subtotal. It's a big benefit to buy everything at once (delivery and handling is a lot cheaper than actual shipping costs), but you can't plan for emergencies, so the cost is lower for smaller orders.
$0.00-$24.99 $4.95
$25.00-$99.99 $9.95
$100.00-$249.99 $11.95
$250.00 and up $12.95"
