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

**LEEVON** · 05-07-2009, 10:57 PM

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.

I meant to say this would be better with less cam. It is more for stock to mild small blocks and great for stock big blocks. Too much cam for this carb causes the rich idle, so if your running say, more than 220 degrees of cam at .050 per BG's recommendations then this is not ideal for you, otherwise good to go. just wanted to clarify.

Great deal. Wish I had the extra cash.

Would you be interested in trading for a Holley 670 Street Avenger?

**LEEVON** · 07-16-2009, 04:29 PM

I appreciate the offer, but I really like the Demon carbs and everything is set up for it, just want to get the 650 speed demon with the IdleEZ base plate.

EyeH8the24 · 07-16-2009, 05:38 PM

**LEEVON** · 07-16-2009, 07:29 PM
