If true, I gotta rework all the math! (hate math. maybe it just hates me.

Any one know for sure?

Ah cool, MBR. TY.

But 6800 is OK? I was shocked when I read that. Seems crazy fast for a 4 smoke

But way cool and yay-ah!

I'm shocked that your shocked that I'm shocked.

Really did have the HFs stuck in my head.

That and my whole riding the short bus in my formative years.

But thanks Again! Really is great news 4me.

Will post a link but CCAT, a manufacturing, state run assistance program is helping me with a design and for the life of me couldn't remember this tidbit.


Anyway, thanks again for the good news. Really fun project.
