I've been doing alot of researching and designing on building up a motor for the venge. I've been looking at building an boosting a 3.0 for the obvious reason that it already has more bhp than the smaller 2.5. theres a 2.5 for sale in the for sale section for 50 bucks, i've been tryin to do some research but sometimes its easier to just ask someone that knows. Can the 2.5's 85.5mm bore be machined out to the 3.0's 91mm? i know they both have a 76mm stroke.
