I won`t hijack the other thread on A/T options for Yblocks so I will start my own. the best site that I know of to research the AOD,AODE,C4 etc ishttp://www.clickclickracing.com/forums/forumdisplay.php?12-General-Click-Click-Tech
The stickys are archived info and there is a forum that can get your questions answered. I have an AOD in my Ford 302 powered Jag Mk2 and I have found this website invaluable to me. Pete
