Like title says, what the biggest cam? Also heads are aluminum ford racing x heads. 1.94 intake 1.52 exhaust.pistons are mahle forged 4.030" on 306 a 9:0:1 compression. Thanks.

 

Take a look in tech at the cam links, there is some good info there and will help give a better understanding and guide you. Also I would consider a custom grind, the price isn't that far off of an off the shelf cam and much better imo. Ed Curtis would be the guy I'd send you to. you can contact him through http://www.flowtechinduction.com/custom-camshafts/. He can design a cam perfect for your setup/needs.
