    Product Description

    BBC 454 to 470 CID with AFR 265 or 290 Oval Port heads to max of 6200 rpm.  If you have built your teenage dream car and put AFR oval ports on it than there is no doubt this is the cam for you.  We recommend a high rise dual plane with the center notched.  An 850HP would be our choice with a good set of 1 ¾” headers.   Don’t worry about gear ratio, it will pull anything you put under it.   Last thing, buy stock in tires.  750 Idle RPM

      Honest business

      Starting from the sweet lady on the phone, who's helped me through endless calls, to the owner of Claysmith who took my engine spec and asked key questions about my targets, he recommended this grind for my ZZ427, and oh boy, it's spot on th money. Thank you Claysmith for excellent products and an honest business.
