How Fast Will A Quincy 6 Go ?

[Jeff Lytle]

I'd contact Frank Novotny and ask him to measure what he has. He has A's through 44 F's so he could measure the diamaters and lengths for you.

I have used floatless carbs on our Mod yamatos & 44 merc`s in NBRA racing with great success. Make the stand pipe slightly longer than what you think you need. Easy enough job to cut down if needed than to make a longer one. Make sure your outlet fitting is at least as large as the inlet and the hoses angle downward to the top of the tank. It is really quite simple to do. And will eliminate a lot of problems with those old Carters. If it were me I would consider a newer more modern carb system.

Regards the several comments about using more modern carbs on the Flathead 6:

IMHO when you have an engine with this history of possibly the meanest sound EVER to hit the race course ANYWHERE, and you are at the place where you are in the project that J-Dub has indicated, I think the absolute worst thing you could try to do would be to try to re-invent the wheel.

The floatless Carters were run very successfully on all classes of Flatheads, from A thru F, and with just the information already posted, it looks to be a very minor part of the project (making the Carters work) because of all the technical knowledge from former Flathead owners, drivers, and most of all folks who built the engines and are still available to give technical advise regards them such as Jim Schoch, Dick Austin, Gene East, the two Franks's, etc., etc., etc.

Why take a chance on burning down or sticking an engine that possibly pistons are in very short supply for, when there are still carbs out there to be looked at, copied, and tech advise is very plentiful for.

Unless Wayne Walgrave is still around to help with the carb part of the project, based on the way he always ran, it would seem to be the best way to go

I do not know J-Dub, but it would seem to me that someone who has accomplished what he has in boat racing to this point, would see the wealth of knowledge and offers to help that are out there and available, and the choice would be a no brainer.

And more than anything if the Carter floatless are used, whatever speed was attained would answer the original question more completely, with the engine in the original configuration the way it was run 40 years ago, which is, HOW FAST WILL A FLATHEAD SIX GO?

Whatever decision is made, it certainly is his to make, but for all the above reasons, cost, time wise, experience with them, ease of adjustment etc., the Carter floatless with all the information about them available, just seems to make good sense.

Whatever happens, I hope the project is brought to completion, because as Wayne mentioned, there are lots of folks waiting with much anticipation.

I think Rick Fales has his fathers 6 looper. Last conversation was it was in pieces. May try to contact either Rick or Steve to see if the carbs are there and can give you some dimensions for the stand off tube. Bill's was one of the most powerfull if not the most powerfull 6 looper in its time. All the comments in this thread are all accurate. Floatless Carters are almost fool proof. Please keep all of us informed on the progress......Bob N-96

Remember that there is a difference between and looper carb and a deflector carb. The loop carb has a fix jet drill into the tower.

Dick,

All my Carter float less carbs had adjustable needle valves.

[Tim Weber]

Here's a question.

What type and pitch of prop will this monster pull? Ron?

This is fun to watch.

Yes they all have adjustable needles, however the loop had a jet hole drilled into the tower directly across from the adjustable needle. This kept the adjustment in the 1 1/2 turn range. That jet (.0625) hole was the difference in the fuel demand of the looper to the deflecter.

Everyone missed one point here. J-Dub has been in regular contact with Rich Fuchslin. Now maybe I am biased here, but I think Rich has a pretty good handle on making a 6 cylinder run, either the Merc or his big looper.

Joe

[Gene East]

Your point is well taken!

However, I don't think anyone who has contributed here would ever discount anything Rich has to say. He can put his record up against anyone and not take a back seat.

We ALL want J-Dub to succeed and he couldn't have a better mentor than Rich Fuchslin!
