The short travel Johnson's were quoted at $740. maybe I should look around. I would like to talk to Craig about what spring setup works best but I can't find any contact information anywhere.
I really don't get the short travel lifter thing. Just measure for pushrod lenght and get a pushrod .020-.030 longer. Or less. Not sure of the growth amount on these g3 but i assume its around .005
If you have fb you can get Craig on messenger. I have his phone number but it might be his personal number I really don't want to give out
