I thought that these blocks don't have too much meat to Bore them, let alone .30... I have no idea from a knowledge point but remember having read there no benefit from it. I think a CAM which would definitely help on HIGHER RPM range where these 3.8L flatten out and an IC would probably give the most benefit.
I've been looking at this cause I'm currently going to work on car and plan out future upgrades for later. Anyways, just trying to save ya' from throwing good $ and receiving little(HP) in return from it.
Regards,
