Cant wait to hear how you do at the track!! Good work Chris.

Wow, great progress. Very jealous of all the 6G72 building experience you've got (the critical finer details like honing the cylinder walls, filing the piston rings, fitting the copper o-rings, etc).

Curious though - what made you choose to use a solid tensioner? I've been under the impression that with stock cams, stock valve springs, etc, the stock set-up should be highly reliable.

Yeah, my stock heads and cams comments all the time are kinda misleading, or should I say, wrong. I do have hi pressure springs cause at one point I tested a few different cam setups before I settled back with stock cams. And I never went thru the trouble to remove the springs for stockers.

HAHA... Don't beat yourself up about it. Have you ever experienced the stock valves/springs floating? The general rule of thumb has always been ~8000 rpm's. Have you ever exceeded that on stock stuff? Obviously you took your aftermarket springs to 8500 rpm's this last track visit. You were using the stock tensioner set-up for that, right?

Thought this video was pretty awesome:





Technically, I'm not sure if that's "float" ... Looks like a lot of the people in the comments on these videos are convinced this is just valve "bounce". Either way, the solution is probably stiffer springs.

This was yesterday:

All ready to hit the streets and break the engine in. As usual I will be breaking it in with furious vengeance. Too dark now, and too tired. Time for a shower and snack and tv.



So I will be breaking her in today! Giggidy Giggidy
