Make sure you talk to KEITH, if you listen to me you might get Fu**ed. He is the only one that knows if it is a steel billet or SADI core. You use my gear on a SADI core and it will destroy it. This gets back to you should have called KC from the get go!!!!!!!

Visually a SADI core looks much thicker between the lobes than a steel billet. The one you see on Summit and Jegs pic are usually SADI, in order to get the steel billet you need to special order. Gets back to talking with your engine builder.
