Use a 72 up block, the new lakewood to chev bell and most any good trans is available w/gm bolt pattern and a multitude of gear ratios are avail. Blowproof clutch & flywheel are MANDATORY w/500 hp! BTW- before lakewoods you had to make a .250 steel enclosure around the bellhousing 360 degrees. Blankets were not made until later and could ONLY be used on automatics. Been racing since 1963, seen some clutch explosions, nasty....... amxron 70 AMX 70 Hornet 78 FSJ Wagoneer Fleet&JEEP Mgr Orbit/AMC-JEEP 50-1787 _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
