Yep,I know Harold very well have spent hours with him in the UD days. I can assure you the 114lsa cams are not getting moved to 110 as the OP stated,if a grinder WOULD do so I'd run. You think the same rules apply to a Billet cam core as a cast core? LOL Even a Billet core has limitations and we aren't talking about anything other than a factory cast core. Thanks for helping me understand. Kinda find it funny a guy tries to quote someone that I've known in person for 25yrs. Too funny.
