ok, so 3L's NA ehh. That would be helpful, now would this 3L's come from stroking or boreing or both, cause if its a lot of stroking it would restrict revs which for NA even with 3L's wouldnt be good! Otherwise yes Im interested in more displacement, $2400 isnt bad(also isnt our block iron, if anything this would be lighter not heavier!) for what you are getting, skrillas site gave all the 2.4L info and it appears that the 2.4 really gives a great increase in power, so I think .6L would add a fair amount, even just 120hp per l would give 360hp, time to kill some vettes!!! Anyway Im very interested, just gotta start saving money.
