December 30, 1999What is the best way to tell a 351M crank from a 400M crank when placed side by side,Thanks.
Klamath Falls, Or
December 31, 1999The best way would be to use the casting #`s.
The 351M crank is actually a 351W crank. Look for the 351`s 1/2" shorter stroke in the rod journals.
December 31, 1999The snout on the 351M is apparently different from the 351W. That`s why a 4" stroke Windsor is no easy task without some fancy machining. I think it was Coast High-Performance that had that info - can`t quite remember.
As BroncoJ says, measure the crank.
August 15, 2011i am wondering what the benefits are of a aftermarket crankshaft kit? after that, what is the best crankshaft kit?...
