Thanks BYprodriver. While I've considered upgrading, I think that I'm going to ultimately stay with a 2.7. If I upgrade to a 3.2 or a 3.4, I'll need to upgrade the oil cooling system, front body work, DME and I'm sure a few other things in addition to all of the regular stuff like seals, clutch, IMS bearing, chain tensioners and guides, spark plugs and so on.
Maybe someone else reading this would be interested though. Thanks for the suggestion!
