I'll lower the timing when I get it back together. I was counting on the MSD BTM to pull the timing back but how do you tell if it is. I suppose a chassis dyne would be the only way. Your system is a little to expensive for me right now. Maybe over the winter. Pistons look just like I got them from Tom. Some carbon on #1. I don't know what my inlet temperature is but it is noticeably cooler coming out of the intercooler. My first 2 runs were aborted because afrs out of range (high 13s). The last run when I hurt it was 7.76 at 82mph in neutral coasting. I was surprised how good it felt. It's in a 3300 lb. 53 studebaker. The 500 cadillac I used to run in it had best of 7.78 1/8, 11.84 118 1/4. I'm sure this is going to be a lot faster. But I've got to keep it together. Thanks for the help.
