It's not that i WANT to rev my engine to 8400rpm it's the fact that i CAN! It doesn't happen very often and it's not a stocko 120Y auto that gets driven to uni every day. So if i want to i will. My 1200 doesn't have rego and it gets trailered to any event that i do. So if it does go bang SO WHAT..... $300 at a local wrecker will fix that prob and I lose a weekend working on the car. I was just stating a fact so please chill guys...

Matt

I knew a bloke who had a reallt worked A12 in a racecar. He used to shift at 9500rpms. No prizes for guessing what happened to that motor...................................BANG!!!!!!!!

Ahhh very entertaining people, I havent laughed this hard in a while.

Thankyou for making my day.

I've got to stop reading this thread!

thats just what i was advised to do

10 minutes to get oil back in to the oil galleries? Is that right? I find that pretty hard to believe...but I don't know much about the mighty A series engines. Couldn't you just use some pre-assembly lube?

The occassional rev to 5,000....well I guess that's better than "9,000"....and I heard what you said re: tacho reading incorrect, I just don't see the need for free reving like that......but that's just my oppinion.

Good luck with it all......hope you get the bugs sorted out.

well actually a performance cam should change the characteristics of the rpm curve by increasing the peak engine performace/ power and the capability beaing its max rpm. if i had a dyno handy i would have some data that i could work off, but i dont

loose tappets become noisy at increased rpm, too tight and you will lose compresion, i slowly tightend them until they made no noise

and yes, the pushrods that i got were infact a14 pushrods as the guy i purchased them from thought that i had an a14 because of my head and said that they WERE a12 pushrods. But the guy he brought them from told him that a12 pushrods were hydrolic and said that they are all the same lenght, whith the right ones in place they where approximatly 15mm shorter

it sounded like you do this as a matter of course, like its some measure of engine performance or capability? Its pointless - it achieves and proves nothing. And certainly isn't useful for checking valve clearance.

btw, what ended up being the problem with fitting the rockers after you installed the cam?
