Thanks heaps for the replies, and sorry for the confusion, what I meant to say is they closed the bonnet on the rpm pick up unit, which damaged either the output plug or the pcb, if you hold the plug just right it will pick up, but unreliable .. The oil is magnatech, and will get changed when I do the bike, the diff is an LSD. I wasn't on here to make it an issue, and the car goes about 4million times better that when I got it 2 years ago. I just wanted to show the ol girl off special for the cam say peak torque is 4200rpm, but am interested what you meant by the reference to 5252rpm?.
Again thanks heaps, hopefully I cleared a few things up, and would love to hear your thoughts
