The C grind is what was available at the time that we were ready to install the SC. I know that VPD now offers a cam intended for the SC, which would certainly be a better choice. This was one of the things that fell into the ‘what’s available now’ category.

The head was ported. Unfortunately (and as with many port jobs on these heads) it didn’t improve flow over stock on the intake side. John (Parker) didn’t do the head – if he had, I’m sure it would flow better. Somewhere I have the flow bench numbers... I think. When comparing to a stock head, we used an E as the baseline - which isn't the same as an F, but would (hopefully) give us at least some ballpark info.

Re: the rods: I’ve heard (dangerous to put faith into rumors, I know) that these rods are weak and that I ‘should’ have used M rods.

In the end, I think what I have is the setup that worked well based on the R&D that had been done up to that point. In the last several years, further improvements have been made that have resulted in better performance and economy than what I have. But I don’t want to start over – what I’d like to do instead is make the best of what I already have. It might not be optimal – but it’s still an awful lot of fun. If, at some point, I have reason to pull the head, I’d like to change both the cam and head.

Until then, though, I’ll be happy to work with what I have and fiddle with things on the outside of the engine.

Best,
