[/COLOR]Yeah you need it re-curved cause even 38* is quite a bit for a LA. Too bad you ain't close. I've done numerous distributors. Doesn't take long at all and really makes a big difference.

That is a kind jesture, thank you!

Do you smell any gas when you nail it and see your gauge moving?

Could someone have drilled in the trunk and gone through the top of the gas tank? I've heard of that before.

Pull your plugs? Are you running rich? Are the plugs wet fouled or black?

My 68 340 Formula S with a 3.91 gear screams at 4000 k at 70 MPH with a 650 Double Pumper. MP .484/284 cam with Rhoades lifters, stock converter and I get better mileage than that. (not sure of the tire size, but taller than stock).

You'd better shut that thing off when you fill up with gas, you'll gain on the gas pump and never reach full.... LOL!

I would check for gas leaks to make sure that it's not leaking out. Second see if you're running too rich. Then chase "more efficient" components...

Could a neighbor be siphoning your gas when you're not looking???

No, no smell of gas anywhere and the car stays parked in the garage.

I pretty sure everyone is onto something with a good tune!

My 02 cents: 360 ported heads/2800 9.5 GER converter /3:55 TracLoc./" those 275/60/15's " actually measure under 27"...(750 4779 d/p) : Was getting 21-22 MPG@62 MPH,with vac advance hooked up & a vacuum gauge. Your can is smaller,pay attention to the small details.

Thats a nice set up. I will look into those tires to start, thanks for the heads up on them.
