Once again, my Lemons car lives!

[parkwood60]

Thought you guys might appreciate this. After 99k miles, and 600 racing miles the original 3.3/200 died a slow death. Postmortem revealed the last 3 hours or racing had been done with the #1 piston cracked right down the middle.

And so a $200 motor was purchased from the driveway of some guy who had parted out a Falcon. After dragging it home I discovered a serial number tag epoxied to the block, and a 2002 date stamp on the head, confirming my suspicion it had been rebuilt. Some fabrication was done to convert it over to Fox body use, the stock smog exhaust manifold was chopped and sealed leaving 1, 2 and 6 cylinders opened and a 4 cylinder motorcycle header was chopped up and made into a header for those ports.

Yesterday we got it running

Ignore the smoke, I put a bunch of oil down the intake and plug holes before trying to get it to start. But you can't ignore the fire!

Still a bit of tuning to do. Anyone know if the stock 70s Holley 1bbl uses standard Holley jets?

If you can find a used one a 500 cfm 2 bbl holly works great if you plug up one of the barrels and block off half the metering block.

I've got plans for other carburation, but not for the race 2 weeks from now. I have 2 big Carter YFs, a Rochester 2bbl and access to a set of 1bbl Webbers from a VW bug set up. I am on a constant time/money constraint and have to manage expectations of my drivers as to what we are going to do between races. The race after this one should have us with a rebuilt 79 motor with the good big log/valve head and more carburation.

hey great, you might try the rochester 2 bbl, the 1 1/4 small design. we first started racing our foxbody. i made an adapter fit, and modified that small carb and it ran quite well. got us in a stock body down to a 9.99 1/8 mile. and it was bulletproof. and best of all, cheap!!

I have a set of 750 honda motorcycle carbs, crane valve springs & retainers I would sell.

No thanks, I think I already have 8 or more Honda carbs, though some are still on a bike. Wrecked bikes are pretty easy to come by here.

Howdy Back Parkwood and all:

"Anyone know if the stock 70s Holley 1bbl uses standard Holley jets?"

I don't think standard Holley two and four barrel carb jets will fit in the late model #1946 Holley one barrel. I've never tried them so I'm just trying to recall, from somewhere. The #1946 Holley carb was fairly well sealed up and not user friendly due to FoMoCo trying to lock in EPA requirements of that era. IIWY, I'd either run it as is, or try one of your other carbs that are a bit more tuneable.

Adios, David

Yes! They will. I have a Holley 66 jet in my 1946.

 

[parkwood60]

Thank you kindly. Any idea what the stock size was?

 

[xctasy]

Yep, according to JackFish, 61 jet.

Lincs 200 used 64's.

This thing ran great, and sounded awesome all weekend long. The homemade 3-1 header didn't crack, and the stock exhaust manifold with ends plugged didn't leak. The motor held together even with an accidental rev up to 6000 when I caught N instead of D on at least 2 occasions.

As speeds went up we started to get a fuel starvation issue in left hand turns. I'm thinking of switching to the early fuel pump with built in filter to get more fuel volume up front in the event the starvation is coming from the fuel sloshing in the tank out back. Anyone know if these flowed as much as the later pumps? Actually anyone know which of the pumps that fits these motors will pump the most volume?

By the way, we were the 17th slowest car out there, but still managed 62nd out of 171 and 6th in class of 22.

will the rules allow an electric pump at the tank to push fuel forward?what about a larger diameter fuel hose and larger filter? clothes pin and aluminum foil on fuel line! lol

Yes, all those things will be tried, but does anyone know which of the mechanical pumps available moves the most fluid?

I'm actually thinking a big canister style filter, mounted near the carb with the lines on the bottom and a one way valve on the inlet side. I figure I can get a little gravity flow into the float bowl is the pump is sucking air.

How about the Carter fuel pump mod?

Hey thanks, I hadn't seen that post. I think I may put an electric pump at the back of the car and keep the stock mechanical. That ought to do it at least until I'm making big power. And having something constantly sucking from the tank and pushing fuel forward ought to fix a lot of the issue.
