**** At Performance Years: Protek, Tetraethyl lead, 1 quart part #RPZ161 for $12
****Try this stuff for detonation problems. http://www.kemcooil.com/products.php?cId=4 "I use it in my 65 goat with stock compression (10.75 to 1) Along with 93 octane fuel. 3 pints to 20 gallons works well for me. I'm no chemist or fuel wizard but, all I know, is that it stopped detonation under all driving conditions. It's a bit pricey, but, it's worth it to me because it does work. 2 cases usually gets me through the summer cruising season. Good luck."
