Thoughts on Max lead 2000

http://www.maxlead2000.com/

I have heard of others here using Maxlead 2000. What our your thoughts Good/Bad. And what ratio are you using 12oz, 18oz…1gal per tank full? What is you compression ratio both static and if you know dynamic? I am not sure of my dynamic but static is 10.7 to 1.

What is the engine like? Iron or aluminum heads, cam specs, you know the drill.

I am running 10.2 +/- static CR and 8.2 dynamic CR, if the charts can be believed, on 89 octane with no problems. I do have aluminum heads. Timing is 36* in by 2500 rpm + about 16* vacuum. Cam is a CC XE274.

I am not sure if I need it or not. The engine was just built and has not been started yet because I have not picked it up from the shop. I want to make sure that I don’t harm the eng before I even break it in. It does have aluminum heads and the cam specs are as followed. As for the timing I don’t know that either I would like to set it to make maximum power. I am not sure how to calculate the Dynamic compression ratio.

93 oct. and timing at 36 deg. should be fine for break-in...your not going to be running it hard then

I will try not to at least. I do have a mental condition that makes my foot get very heavy when “rice” with coffee cans and 6 story spoilers or a Ford get around me.

my 70 -11 to1 350 loved that stuff. Mixed a qt with a tank of sunoco ultra. Other than that or AV 100LL, (the vette loves that too),and all I heard was pinging.

I rebuild again after a bunch of years years, and I'm running on ultra only, with no pinging at all. Wonder if I had issues before.
