I thought the 290 came in some CJs? The center hole is in the 290 & early 304/360 but not the centering ridge that 727s and later STD flywheels use to align. The adapter on mine fits into the pilot hole and has no center ridge. Just the holes to bolt to the flexplate, which has 2 special bolts with alignment dowels to center the torque converter.

" The early motors didn't have a crankshaft centering "ridge" around the " pilot hole like '72 up did. They used the outer edge of the crank " flange and a step in the back of the flywheel with a pilot bearing in " the flywheel. so '71 [and earlier] v8s -didn't- have a pilot hole in the crank? '71 would've seen the last bw autos in amcs, '71 the switch to mopar autos. i was thinking '73 for cjs, which hadn't had v8 power before. logical that big jeeps would've replaced the buick 350 with native power asap. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought -------------- next part -------------- An HTML attachment was scrubbed...
