I think the early 4.0L cranks matched the 258 crank. later on they enlarged the first step in the crank to the 1.81" diameter. The bushings for the 258's are about 1.056" or so O.D. I'm reserving judgement till I can get the stupid thing torn down to take a look at it. -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 2004 Grand Cherokee Laredo, 4.7L, Quadratrc II " Chronic Pain Hurts" -------------- Original message ---------------------- From: adh@xxxxxxxxxxxxxxxxx (Sandwich Maker) > " From: Wrambler242@xxxxxxxxxxx > " > " Did some more cyphering on the pilot bearing into the 4.0L needed for the swap > to the Ford trans. > " The exterior of the adapter ring for going into the rear of the 4.0L seems to > be 1.81" going by Andrews number. > " [] > " Might be a better idea just to go for a T150 bushing and have it machined to > the press fit for into the 1" I.D of the adapter. > " What's the Pilot hole on a 258? > > according to dino savva over on the strokers list, the bushings for > early 4.0s [with the 1.81" od] also fit 258s. that makes me think > the t150 bushing would also be 1.81". > ________________________________________________________________________ > Andrew Hay the genius nature > internet rambler is to see what all have seen > adh@xxxxxxxxxxxxxxxxx and think what none thought > _______________________________________________ > Amc-list mailing list > Amc-list@xxxxxxxxxxxx > http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
