I haven't thought about having plugs for the track. Good idea! I'm thinking of running the autolight. Platinum 65's in it. I have crappy. Copper 63 in it now. Could be part of the issue also. I wasn't sure on what heat range to run in it so I ran the colder 63. What's your all's suggestions. On spark plugs I should be running? I was worried about the comp. And the pump gas with the 10.2 comp and iron heads. The chambers are polished though. My cranking pressure right after I broke the cam in was 180 psi to 185psi. I haven't checked it since I've put a few miles on it. Probably has 1k miles on it now. The exhaust is so loud right now I can't hear for spark knock. That's why I check my plugs a lot.
