Never had a Y block vapor lock, however I did have a chrysler 300 with a 440 that did, when I bought the car it had all kinds of tinfoil wrapped under the carb, put a kit in the carb and that was the end of it, drove it for 10 years after that without a problem. If you block off the exhaust passages, run a line to them from a windshiled washer container and fill it with Ice and water, turn the pump on and you will have an intake cooler!

I have a set of the restricted gaskets on my 56 Bird. Went from NJ to CA and back (6300 miles) and no sign of paint burnoff on the intake. I get mine from CASCO, TBird parts supplier. Some say they are truck gaskets.

Thx EJ...coil's brand new (I had the same thought). It does seem to be in a rather warm spot, but it's in the stock location behind the carb on the passenger side. I'm thinking of mounting it on the firewall or inner fender just on general principal, but the stock location seems to have worked for Henry...

You have posted the same post that I posted a few years ago. I chased everything there was to chase on the fuel system. I changed fuel pumps, checked vents, replaced the metal fuel lines to the motor with rubber ones, blocked off my heat risers with a strip of metal ( I just loosened the manifold & slid them in & tightened it back up). I installed an electric fuel pump to no avail. Normally mine would only do it at idle or poking along like in a cruise. Finally it did it going down the road at Turkey Run in Daytona & I was dead in the water along the side of the road. My son was with me & he touched the coil & it was hot as hell. I had never believed it was the coil (as some on here had suggested) because it was a brand new Mallory coil. I went to Advanced Auto Parts & got an MSD coil & have never had another minutes problem with it.

Restricted crossover intake gaskets, if not available in your local, are likely available by mail from Gasket City, Hamilton Ontario. www.gasketcity.com or 1-888-335-4686, toll free (eastern time) He advertises in Hemmings & has a huge inventory of seals & gaskets..

I think they are Best Gasket brand and Mummert probably has some. I have restricted gaskets, and absolutely no heat issues, even in stop and go traffic, here in Atlanta, in the summer.

You dont need special Gaskets.You can cut a small piece of Tin or Metal to cover the openings in the Heads before you put the Gasket in place.In other words cover the Crossover completely instead of using the restrictor Gaskets to partially restrict heat.There is also a blank spacer plate available to replace the Heatriser altogether.Most of the specialty Suppliers like Tee-Bird etc sell them.

  

Where did you find restricted gaskets? The parts stores here only have the unrestricted ones.

When I bought my car everything on the engine was new and had new paint. The paint soon blistered on the exhaust crossover under the carb. The first thing I did was wire open the exhaust heat riser and that helped a bunch. The gasoline was boiling in the carb. (Carter WCFB) yours is already done.

Next I added a 1/4" phenolic spacer and the problem dissappeared. (I checked the fuel flow by pumping it in a can all was good). I added a glass bowl filter in the fuel line and placed it about where the 57 bird is done above the intake at the #1 cylinder which is in the air path of the fan. I also used steel tubing to the filter and from the filter to the carb. Bought a flare tool and multisize bender from Harbor Freight; great for the garage guy.

Engine temp runs right at 170 at the thermostat housing. I have a lazer temp gun (Harbor Freight too) to read stuff at times on the intake, exhaust, and other places. The fuel line does read higher than I like sometimes in the 140 range as it passes over the exhaust crossover area. Going to put in the restricted intake gaskets soon.

The last thing I'll point out is the gasoline we have today is liquid junk. You may want to put in an additive with every tank. I use Sta-Bils product for help negating the ethanol..............Good Luck

I'm going to replace every bit of rubber hose, carb to tank this w/e to eliminate those as possible culprits. The fuel pump is a new (reman) from Cardone; I put it on after the problem cropped up. The car runs fine until it warms up, then falls flat on its face. If I let it cool long enough it will run fine again until it warms up. I'm still leaning toward vapor lock...
