Default Coin Flip For Cams
New 107 build and still needs cams. Cylinders and new pistons, 10.5cr, are ready for install. Ported 110 heads ready also. Porting done by Greg Dahl. Now for cams I am considering either S&S 585 or Tman 625. Give me some opinions or I flip a coin.

We all need to know the chamber volume first. And head gasket.

You'll need a domed piston with that 110" head on that 107" with either cam.
The .585 would/should show more of an hp charge, and the .625 should hit harder off the bottom-mid.

If you have a true 10.5 static and the heads are setup for the lift; TMan 625.

I ran the 625 in a 103 Stage IV engine and it performed very well. I have had more than one cam from TR and can attest to their performance.

What did Greg recommend for cam. The S&S 585 with SE 1.725 rockers on the intake side only works great with that or slightly higher compression.
