Comp cams
Not a question, just a heads up for guys about to drop some coin on a camshaft. Comp has their stuff marked down to ~$175 online. Which is almost $100 cheaper than most bike sites sell them for, Summit sells them for what Comp has listed. Just picked up a TC-3102 myself.
Cheers

I got the TC-3102, had to wait for Comp on the #850 lifters. Everything went in, but have been too busy to schedule any dyno time. Just running a map from FM for an Andrews 57h that I ran autotune on.
Word I got was Sheffer? HD over in Indiana has great luck with these, haven't spoke with them personally

Please post dyno results along with any other motor mods and basic cam profile, i.e, intake/exhaust open/close; lift; TDC lift, ground in advance and duration. Not a common cam choice but always interesting to see results from different stuff.

Wouldn't be bad if it wasn't for the 3.5° advance. Not much for hp. They'll be toast before 5500rpm. Some might like that.
Similar to the 204s with more lift.

It's basically an Andrews 57h. I bet it'll peak around 5500rpm. Look at the published lobe centerline's of some "popular" camshafts, you'd be surprised how many of them are ground this way

Be interesting to see how they do and what your tune looks like. The moco has a dip in timing somewhere around 3000rpm WOT for their stage 2 w/ 204s base cal in the SE Pro Super Tuner software. They have a 4° advance grind as I recall.

It'll be close. Depend on the exhaust really. I'm not saying they're bad by any means. I just prefer them to rev a little higher and the 3.5° takes it the other way 200-300rpm. They'd be similar to the S&S 570s I run too without that 3.5°. They're done at 5700.
