Barry Grant Road Demon 725cfm - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Barry Grant Road Demon 725 with vacuum secondaries and electric choke. I rebuilt it last year although it didn't really need it and I have put very few miles on it since. The truck it rests on is rarely driven and always garaged. I also have the original paperwork for it.

If you aren't familiar with these carbs, they share much of their engineering with the trusty Holly 4150's but are much improved. Almost all of the parts interchange such as gaskets, jets, accell pumps, etc.. I love this carb, it's a screamer but it's too much for my small block 350, it would be better on a big block or with more cam. I could never get the idle circuit tuned just right. This is not a symptom of the carb, just the wrong application. It will be shipped clean, but not as shiny as these pics, they were right after the rebuild.

$275 plus shipping

please reply in thread as per forum rules.
