go to the AE web site and start with Blackstocks setup - it is a good starting point for the 12L4
ps Mo Denton (a top driver-check results for the 2005 on roads in Cleveland)whipped everybody at Y-City on new years day and thats what he was runnin.........
Also check out Mike Lafaso's web site - he placed 4th in 12th mod with a 12l4 - I think he beat Blackstock and that's tuff!
