Final thoughts....
Carpenter Racing is a small business, they dont have a receptionist or any admin staff. I've never had a problem reaching them, but I have heard that others have. A little patience and very likely Bob himself will answer. Everyone I spoke with at Carpenter was curtious, helpful and had an answer to my querrys and questions.
A few things that I discovered along the way:
Carpenter set the valve clearance fat. Its my belief they do this as you now have stronger springs, new retaners, etc and will settle some as its run in.
The rings are a TIGHT fit. Follow Carpenters guidance unless you have more experience than them! I was told they are ordered to Carpenter spec.
I never really did get a straightforward answer on the break in proceedure.( if you research this, everyone has an opinion!) So I followed my experience with a couple of high idle heat cycles and ride it!
The stock starting system CANNOT crank this much compression. Not even one rev! So consider at a minimum a heavier ground in your plans if you decide you want this. The 1.4 kW starter IMO is what's needed to handle this kind of cranking power.
Run premium fuel. Running on 87 octane is nonsense. I was getting detonation with 93 during the tune, so unless you want to do this twice go with premium fuel.
Of course all of this is just my 2 cents. I don't know it all!
