" From: "Mark Price" <mprice@xxxxxxxxxx> " " Also you may want to check out the AMC Forum if you can. " Under transmissions a guy put a Tremec 3550 in his Javelin if the " AX15 is as tall as the 3550 you are in for a bad news kind of day. " He cut a real big hole in his trans tunnel to get it in! the ax15 may be big, but i doubt it's as bulky as the tremec. that's based on the ford toploader, designed in the mid-'60s to cope with muscle car big blocks. is the late-'70s tunnel that much bigger? that's when amc used the tremec t150, also a ford toploader. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
