im sure u have good shops in kelowna but jims engines in prince george is a good shop,moparwise, jim races a 408 himself, very knowledgable and wont rip u off, he actually talked me out of some things i wanted done, things that are recommended on here and other sites, but hes seen on the dyno its just not worth it. im sure your build would be in budget there, plus it can be run on dyno if u wish.just a thought,thats where im going to this winter for a 408 build
