T-man cam selection for S&S 100" big bore

[Hossamania]

I think you will notice a little better response than the 88" motor....

Good choice ,have fun

I ran a S&S .600 cam in a 4X4 100" Evo in a heavy bagger. very pleased. The .585 in a lighter bike like your Dyna will have plenty of low TQ, and a rocket up top.

 : Awesome build. You could even lean on the compression a bit more. That's going to be a blast in your Dyna

Thank you all for the good replies. So now my bike is in the shop. I let the professional to build whole package. This is the setup:

- Crank will be balanced, pro plugged and welded
- S&S Big Bore 100" with 10.5:1 CR
- TC96 stock heads, porting work, bigger intake and exhaust valves and valve springs
- S&S Easy Start 585 cams
- S&S 52mm throttlebody + S&S air cleaner
- S&S lifters and adjustable pushrods
- V&H Pro Pipe with competition baffle
- Power vision + dyno

Hope there is some difference to a stock 88

Like already mentioned a little more squeeze will wake up the bottom end. Play with the big boyz calculator the 585's are very happy @ 195ccp.  Bob

That .585 can very easily leave a LOT of low-end power, missing from the mix.
Not being a wise guy, but we really never reach for that cam.
Just our choice not to.

What would be your cam selection for this setup?

I'd suggest sticking with the plan your builder laid out for you, if he's done this before. Here's a great example on a dyna http://harleytechtalk.com/htt/index.php/topic,113883.0.html

Yes I am sticking with the current plan

Oilpump was a not a best condition anymore so we replace that too with: Screamin' Eagle Billet Cam Support Plate with High Volume Oil Pump
From original TC88 I have left engine block and flywheel

Did you check mthe pinion shaft runout.  Many poor oil pump conditions are the result of excess runout and it never gets better on it's own.

[jannejk]

Runout was 0.075mm = 0.0029in. Flywheel will be balanced, pro plugged and welded also.
