I don't have a specific parts list yet, but here is what I could find, which are the details of the kit from when Tom still openly offered it on his site:
2.3 billet stroker crank
Custom Forged pistons
New rod and main bearings
ARP Main studs
This may not be entirely accurate though; similarly, some of the cost of the kit may be for installation labor. I'll talk to Tom and see if I can get him to chime in with a confirmation of this list, or to provide an accurate list of parts.
I need to talk to him anyway to see how using one of these kits would impact the cost of a freshly built motor from him anyway, since obviously some of the parts he would otherwise use won't be going into the motor, etc.
