Go over to SBFTECH.com

There ia a guy there named Jay Allen. He is Camshafts Innovations. He only makes billet cams.

If you do some research on there, you will find out all about the difference in cam cores. SADI vs. Billet cores was a big discussion on several post. From what I see he loves to do solid rollers on the street.

I am seriously looking to have him do my cam/valvetrain in the 306 I am building.

Be careful what you say or ask, they are a tough crowd if you don't know your shit!

But they do seem to know their shit though! All around it looks to be a great site!
