Re: GM Forged Rods on Turned 401 Cranks

[lynn peterson <kustomkemps@xxxxxxxxx>]

Not only do you save a pile of money, you reduce the
bearing speed, reduce reciprocating weight, and
increase the stroke all at one time. Just takes a
little math work to figure it all out. For example, a
401 crank cut to a 2" SCB small journal size will
offset grind to ~3.92, somewhat less if it has been
previously ground. With a 4.28 overbore, custom
pistons with a CH of 1.123", and 6" rods, a 451CID
engine results. We have built several of thses with
great success. Of course, there are many other
possible combinations.
