Trying to get some info on my Senator no 140 it was ordered by Patterson Cheney in Melbourne very optioned up with spoiler driving lights and leather bolstered seats but the main thing is its a factory manual and when we took engine out for a freshen up it already appeared to have a bigger cam from factory the engine had never been out before i took it out HSV verified it had a lot of options for a base senator and suggested it may have been ordered as a dealer principal car and as i know Patterson Cheney were big HSV dealer but couldn’t give me anymore info about build numbers of the manuals or any other info if anyone could help out with some history of this car would be great
