I'm gonna install Rob's Cat Deleat pipes on my Graphite car then I will start runnung 100 LL (100 octane low lead) av gas.
I run av gas in all my old cars, even the Model A which has a compression ratio of about 6 to 1. The valves on these old flatheads need a little lead for the valves. I don't see why the SRT6 wouldn't like it. Plus av gas doesn't stink. Any comments?


It must be hot sh-- to be drivin a Crossfire at the age of 16. I drove a Cushman.
