As far as I can see the only reasons for fitting a Holden engine are that it was cheaper than overhauling your clapped out 2.25, and parts were easier and cheaper to get.

Thats true but instead you got a backyard engine change with an engine that didn't suit the vehicle at all and that was only good for chewing out the pinion bearing in the gearbox.I've had one of them too. Pat
