Max Lead 2000

[John Lokay]

I recently registered to participate in the National Road Tour and will be driving my 66' L-72 coupe. Given its high compression engine (11:0 to 1:0) I have to make sure that I'll be able to feed it high octane gas during the trip. When I drive the car locally, I mix 5 gallons of 111 octane cam 2 with a Texaco 93 octane and she runs fine. During the Road Tour I would rather not have to carry 4 or so 5 gallon jugs of cam 2 in the back of the coupe. So I am thinking about using Max Lead 2000 and would like to hear feedback from the DB on any one who have used this product on extended trips. Thanks

Have you considered retarding your timing slightly for the trip? I'm sure someone with deeper knowledge will weigh in...

Re: Max Lead 2000

Do not have a world of experience here, but will offer this. When I purchased my 435 I contemplated the same things as you (The previous owner had 110 in 55 gallon drums). Finally said to hell with it and put in unleaded pump gas. I like simplicity. Car still runs like a bat out of hell and does not knock, ping, etc. Never changed timing or anything

So why not just put in some gas, go out and have a good time to see how she likes it? If it pings play with the timing a little or put in a bottle of lead any see what happens. I agree with you carrying around unsecured gasoline cans in the back of your car is just trouble waiting to happen!

I have it for a few years and find it very good. I have a 1963 Z06, with about 10 to 1 CR. The longest trip I have gone on is about 180 miles with no problems. I used to use 104 cam 2 now I just mix the Max Lead with 92 Premium.

Re: Max Lead 2000

Dave,
When you used to use the 104 Cam 2 I assume that you mixed i with regular pump gas? If so, what was the ratio of cam 2 to pump gas that you used? Also, does the 104 designate 104 octane? Thanks

Why bother. Pump premium works well in my 1970 350/350, and regular (no alcohol) 87 works in my 1960 FI with 10:1 compression. Save the luggage space for tools and spare parts!

it is aginst the law

in some states to carry gasoline in containers in your car and even in your race car trailers which some racers found out the hard way and it cost them money.

Re: it is aginst the law

Which states?

Re: it is aginst the law

John The stuff doesn't work. There have been many discussions on this but the gist is you don't increase octane by pouring lead into the tank. It's a more complicated chemical refining process. Buy the highest octane pump gas you can find, retard the timing a litlle and go easy on the pedal.

i do not have the article any more but it was in a racing magazine warning racer going to fla. for the winter races.

Re: Max Lead 2000

I used the Cam 2 104 right out of the pump. You could buy it here in FLa. When I lived on LI I used to pick it up in 5 gal jerry cans at Gasoteria in Commack. The 327 360HP has a CR of 11.25 to 1 but is lowered by adding a second head gasket to about 10.5 to 1. It is strange but the factory had on on correctly then the second gasket was put above the first upside down. I saved the gaskets when I rebuilt the engine about 20 years ago.

The lead is in the gas to protect the valve seats and provide a lubricant. I did not notice a difference in knock suppression between the 104 octane and the 92/93 octane with the lead. The leaded gas has a better odor, like the old days, and I find the engine fires up better with the leaded gas for some reason.

One thing I did not like about the original supply I purchase was that it eat through the plastic gallon jugs. The newer version comes in a heavier quart container that is not suppose to be effected by the stuff. I always use rubber gloves and a long sleave shirt when handling it.

Re: Max Lead 2000

go to a paint supply store and buy a case of xylene. put 3 gallons per tank and hang on!

be careful as some of these chemicals

attack the plating on the inside of the float bowls and this will allow corrosion to take place. i can always tell when i rebuild a carb if the owner has been using octane booster.
