Thanks guys. Went through a tankful so I'm a little younger now. One small justice in the World today; The price of racing fuel has stayed the same during the past several months as regular pump gas has skyrocketed. I'm still getting it for $4.99. So a 15 gallon tankful of 10 gallons of 93 and 5 of 110 racing fuel averages out at $3.75 a gallon. So I'm only paying $.61 extra a gallon to run my stock heads and pistons. Not bad.
