If your running an aftermarket ecu then the stock 24tooth and sync triggers are fine for COP. If you don't have 4 ignition drives available you can wire them to run as wasted spark - your still benefitting from strong spark and less moving parts. I've heard that some ecu's with slower chips actually revert to wasted spark at higher rpm anyway just like a lot of sequential injection setups revert to grouped at higher rpm

Rolled it out of the garage today while packing to move house - sooooo want to be working on it but that is having to wait till we are into our new house (next Friday) /useless update

Yeah run till death - slap 6 speed in if its spare

Yep, blacktops like throwing a leg out of bed. If you really want to rev it then silvertop rods are good insurance. They seam to hold together much better with short service intervals. I've seen a few with ventilation ports in the side of the block and the common theme was lots of revs and not wonderful servicing

Nangkangs are pretty good tires, I used to run NS1's and 2's years ago - they actually get a bit better once you've worn them in

As long as the tollerances are ok you should be fine swapping in another crank.
