This is the best Stage II combo I've seen to date.

That's a LOT of numbers.

Here's what I know. I have an air-cooled HO103, with FM intake and exhaust. I went with the CR570-II and... I LOVE THEM.

The ol' "denim dyno" notes a huge improvement in pull from 2200 through to 4500. She'll pull out of a turn with ease and pass anything on the road.

I know this is a thread being pulled out of the closet, but...as I was digging through this thread for some tidbits, it dawned on me, starting with the 103 HO cam specs, what I initially noticed was the exhaust duration was too long and the overlap was off. Then I realized that all the negative noted numbers would signify that they, as noted, would be "after" TDC and "after" BDC. Please don't take it that I'm trying to pick this apart, because I can truly appreciate the effort and desire in having a chart like this for ease of reference and If I'd made this to share, I'd also want to know If I posted any discrepancies. I haven't looked through anything more other than what I stated and have referenced what I have known to be the specs of the HO cam above the chart and have verified as much as the input numbers give, on BigBoyz cam comparator. Again thanks MR-Wizard for the effort in creating this chart!
