(they only had 3.08, 3.23/3.27) from memory. it will sit on 2300-2400 ish rpm at 100kmh all day every day forever at that. if you decided to modify it, then you'd look at a driveline from a donor vehicle(barra from BA onwards etc is popular these days.. but it's not easy and i wouldn't do it) i'd stick with the crossflow personally.. good reliable SIMPLE engine, can change a starter motor in 4 minutes and an alternator in not much more time 1 roKWiz reacted to this Share this post Link to post Share on other sites
