Re: [Amc-list] 390 vs. 401 crank casting numbers ....

["Armand Eshleman" <aje1@xxxxxxxxxxxxxxx>]

Greg,

I thought I read somewhere about clearance problems putting a 401 crank in a
304. Could you please confirm that the 401 crank and rods actually fit into
the 304 block without interference problems?

Gang,

IIRC cast cranks have a very fine parting line,
& forged cranks have a larger wider parting line

304 and 360 used cast cranks, same stroke.

390 and 401 are forged, same stroke.

Is this correct??

Can any 304 crank be used for the crank in a 360?



thanks,
Armand

Hey guys,
Got news that the crank for my 304 stroker may indeed be a 401 crank,
instead of the 390 crank ... which changes things a bit ... by +10 CID and
perhaps a few $$$$ for the stroker build.

Does anyone on the list have casting numbers for the 390 and 401 cranks?

I bought this crank from Kenedy back around 1993 or 1994 for $390, new in
the box with AMC bearings. It is the earlier "BW" crank, which I had the
adapter machined into the rear flange, for the 727 tranny. Also had it cross
drilled.

Thanks for the information, guys!



Sincerely,
Greg Taylor :) <><
