10.8 static for the 259 cams is crazy; corrected CR goes past 10:1 and CCP near 220psi. Listen to Scott.......
EDIT: Disregard; a mistake on my part. See #13.

However, I still get 9.7 corrected and CCP at 204psi which is pushing the envelope for a street build IMHO but not crazy at 10.8 static. Talking to Scott still a good idea...

Nice catch. I use my calculator and had a 34* intake close overriding the 47* close from a previous calculation; my bad on the previous post..... However, I still get 9.7 corrected and CCP at 204psi which is pushing the envelope for a street build IMHO but not crazy at 10.8 static. Talking to Scott still a good idea...

Hey Scott
Remember me? I tried the S&S 570 cams like you said, but it didn't have the low rpm torque I was looking for. Can you suggest something with a lot of low end grunt? I ride two up and in the mountains most of the time. Bike is a Ultralimited with a 110"/ SE pro ported heads 58mm TB.

Not as radical of an idle as in smaller 88 motor, as you increase the size of displacement in your case 110 same cam will be much smoother "still little choppy" though... buuuuut not what you were looking for IMHO.
