C/Pro Bonneville Car

Re: C/Pro Bonneville Car

That's correct, you can run as many carburetors as you want and any type you want. You can also run mechanical fuel injection.

There was a '65 Valiant with a Six that ran for a few years. It's now rotting around Whittier or so. I have photos somewhere.

Half the fun of LSR is figuring out the rulebook and applying it to your car. There's about a kazillion classes and you can almost always find a class where you can be competitive, or at least have fun (which is pretty much what I'm doing). Hope you get out to Maxton. We don't have the cachet of Bonneville, but we sure do have fun.

Good luck with this idea. I've heard that the early Barracuda fastbacks ('64-'66) are a bit more slippery than the later ones, and with a slant six the larger engine room on later ones is a moot point. How about three Weber DCOEs on a 170?

Sounds good to me. That's exactly what my dad, who's a big fan of European cars and inliners, was trying to talk me into this morning. I'm currently waffling between that, 2 Holley 2Bbls, or 6 singles, maybe off a bike, which is probably a really terrible idea, but it would look pretty f'n cool. And yes, I know that looking cool doesn't equal going fast.

Re: C/Pro Bonneville Car

I could see potential in six bike carbs. Maybe band-saw the end off a manifold and just attach them with silicone rubber tubing? I've also heard of a manifold sold in South America that used six lawnmower carbs (a sneaky way to get around a tariff on auto parts that didn't apply to garden equipment). But the DCOEs are definitely a well developed solution.

The two Holley two barrel setup would probably be a bit of a pain - while you can get a Weber DCOE manifold for the slant six from Pierce Manifolds, you can't get a two Holley two barrel manifold off the shelf at the moment. You'd have to fab it up yourself, maybe starting from an Offenhauser dual 1-bbl manifold.

I've heard rumor of that too...if you ever find those photo's...or, want to tell me whereabouts in Whittier, I do have a 340 Duster that needs to go to a new home.

Re: C/Pro Bonneville Car

Last I head, Clifford made several slant 6 manifolds, along with headers and such. Something to think about in LSR is that if you can make power without anything sticking thru the hood, this is a good thing. Areo is EVERYTHING! So the Webers will go sideways and not poke out, which is a benefit. I'm not sure on your body, but I think the Holleys might require a bit of a lump. Not that you can't go fast WITH something thru the hood, it's just a matter of how much HP vs how much drag. I think it was last year's March issue of Hot Rod that had the wind tunnel testing on the HRM special - this is worth checking out if you're going land speed racing.

Re: C/Pro Bonneville Car

I had no problem with a Holley 4160 and hood clearance on my '66 Dart back when it was carbureted. Some of the tall air cleaners may not fit though. There's enough clearance in an A-body for pretty much any of the Clifford (or Offenhauser) manifolds.
