103" Done!
So here are the specifics:
I had Don Dorfman from Head Designs by Dewey ( http://deweysheads.com/HDBD_home.html ) Street Port the heads and bore the cylinders to 103.5"
I used KB Hypereutectic pistons
Woods TW-555 cams
Compression ratio is 10:1
Jerry Looney of Looney's Custom Cycles here in Yakima did the assembly.
Mike Stegman of Latus HD in Portland, OR did the Dyno-tune (below)
I am very happy with the results! 114.21 ft. lbs. of Torque and 104.64 HP! I love it. Now if the weather will just warm up!

Looks good Steve, Mike and the crew at Latus do a good job. Look's like Don's heads are working well also. I bet you are anxious for this weather to improve.
I am anxious to see what the numbers are for my SE 120R project when Mike gets done with the install and tune.

Nice Steve, you will be very happy with that build. Sorry I didn't call you back last night, I got busy with the kids.
Your numbers are STD, you can tell by looking in the upper right hand corner of the print out. SAE and STD are just correction factors that are used to factor in variances in weather conditions (simple explanation). STD is a correction factor as well but it's not as strict as SAE though since it reads about 3% higher or so.
