CSX 3000 Series / LeMans float bowl settings
« on: August 31, 2023, 06:29:33 AM »
Ok Cobra Guru's, I might have forgotten the correct way to do this so I am checking with the brain trust. I
I'm running a Holley 850 on a 1st oversize 427  sideoiler in a 427 Cobra. Sidewinder intake manifold with a 3 degree angle when mounted on the engine, lower at the back. Different from  the GT 350 specs.

How do you measure the correct float height? Do you flip the float bowl upside down and measure the gap between the top of the float and the top of the bowl (ie the top once you flip it over to install it) or do you measure the distance from the bottom of the bowl to the bottom of the float, ie. The depth of the area where the gas will be once installed?

People quote 1/2 inch for the front bowl and 3/8 inch for the back bowl, but that only makes sense if you are measuring the depth of the gas because the back bowl is supposed to be lower to prevent spillover when you brake hard.  The car is used for SAAC open track usually as the Toronto traffic requires a ton of planning to go for a nice drive.

And will the slight mounting angle change these numbers?

Any help is greatly appreciated.

CSX 3000 Series / Ethanol, gas
« on: June 24, 2023, 01:36:52 PM »
Up here in the great white north until very recently you could buy 91 octane gas that had no ethanol in it. In November this year Mr. Trudeau decreed that in order to save the environment all gas had to contain up to 10% ethanol. I am running a medium rise cast-iron head 427 side oiler with Hardened valve seats. I have a fuel cell in the car and a single Holley 8 50 double pumper. What are you guys doing when you can’t get non-ethanol gas ? Is there some additive that fixes the water and makes it combustible so that it doesn’t sit in your fuel tank and float bowls ?
Any help would be greatly appreciated

I wait for the annual in paper.

While we’re talking about this, I have an MSD box and distributor. Do I need a ballast resistor?

The Virginia Classic Mustang item is accurate and reliable in my Cobra air car and it has cooked several originals in the past. Brant knows his stuff!

I like the Hurst  shifter better also. Way more positive and less play but no reverse lockout. So I went with the original shifter and changed a bunch of the bushings to hard nylon as well as those two bushings that go underneath the end of the shift lever where it attaches at the top of the mechanism, this removed a lot of the sloppiness. The original bushings on top are rubber and they degrade very quickly.

Hope that helps.

For road racing I used the close ratio with a 3:54 rear end. Good for most tracks except the long straight at Road America and any super speedway. Tops out at about 140-150 mph at 6000-6300 rpm. Not the best for highway cruising but pretty good all round.

Sundude, can you map that old track?

Shelby American History / Preston Lerner's new book Shelby American
« on: February 10, 2023, 07:58:21 PM »
I just finished Preston Lerner's book "Shelby American The Renegades Who Built  the Cars, Won the Races and Lived the Legend". Who would have thought there was anything left to say? Well, if you want a comprehensive, complete, chronological and pretty objective history, this is the book for you.

I have no financial interest in giving this review, but if you are like me, you have read dozens of versions of the tales. Some say the Brits did it all. Others create heroes and villains that didn't exist. Here is a full, accurate, and unbiased history of a very short, spectacular period where a bunch of young guys (mostly) won the biggest races in the world just by out smarting, out working, and out manoeuvring everybody else. And even though Shelby was no angel, he made it all happen.

Thank you Mr. Lerner. Nicely done.
