Re: Roller Lifter Rev Kits for AMC

[lynn peterson <kustomkemps@xxxxxxxxx>]

Crane made them at one time. Don't know if they are
still available. I might be able to dig out the part #
if you wish.I have two sets, which I use with my two
roller engines. You have to be carefull with them, as
they are cast aluminium and break easily.

regards,
