Anyone have any personal experience with them? Know of any good reviews?

The new motor in my Chevelle is running great now that it's been dialed
in a bit better, but my mechanic and I agree that it's not attaining its
full potential, being under-carbureted. His suggestion was a new Holley
750 cfm, (vacuum secondaries), but one of the guys at the speed shop was
singing the praises of the new Demons...

Any impartial reviews out there?

TIA!

Cheers!

This guy liked it:

We started the monster up and checked for leaks, everything looked good. And the test drive proved to be a success!!! The Road Demon was noticeably snappier off idle and had plenty of kick in the top end. It seemed to be the perfect size carb for my little 302. Now granted it performed extremely well out of the box, a little fine tuning should make the blue monster really scream!!!

I've sold both in my shop. If you, or somebody you know, can really tinker with carbs, you can probably get a Holley to to work as good as a Demon for a lot less money.

For racing use the hot carb now is a small company called Willys.

Are you sure you're undercarbed? What are your specs?

383 Chevy, 350-Turbo Trans., Crane Energizer cam (485 lift, 228 degrees)
in a '66 Chevelle Malibu.

Looking for the best possible blend of performance with streetable economy...

The guy I talked to was touting the Demons as the next best thing since
sliced bread... Haven't heard of the Willys, though...

Thanks for the input, y'all!

Intake Manifold, Ignition, Headers, Trany, Rear Gears?

750 cfm doesn't sound too bad, the 600 IS TOO SMALL!

Thanks again, SB...

I assume the Demon they suggest is the Speed Demon 1402010V (750) or the 1563010V (850) for about $400?

I liked Demon carbs when they were called Barry Grants, but they had kind of a supply/distribution problem when they became Demon. Plus, remember they will charge (quite a bit) extra for a choke kit, and you will need new fuel inlet kit too.

Actually, they were recommending the 650 Race Demon (I think...), touting
how much better the Demons flow over the Holleys...

And yeah, thanks for the reminder on the choke kit/fuel inlet expense...
(it's all in the details...!) ;-)

Cheers!

RE: stock geared

I wouldn't go any bigger than a 750/780 then. You'll just loose low end smoothness and burn more gas without going any faster, except maybe at extreme top end.

Switch to an HEI asap. The MSD is top notch, but even a stock HEI with aftermarket parts works great.

RE: the 650 Race Demon

2402010 is a mechanical secondary carb (you don't want that) and has no provision for a choke (which you would want for street use)

RE: "NiceGuy Foolish Price"

I sell the MSD 8365 for $338.50. I would, however, require independent verification of the fact that you are indeed a "NiceGuy". (owning a 66 is worth a few points up front though)

::::sigh:::: that's the problem with stock FI, unless you run nitrous...one feels so inadequate when others talk about their vacuum suckers.
