Just talk to Dwayne Porter (fast68plymouth) who already responded on here. He is one of the best cam person's out there and can grind a custom cam for you. I used a solid flat tappet that I got from Dwayne as I told him my car was a pump gas street car and I wanted a solid cam that had a nice kinda lumpy idle and made good power and had to keep my cyl pressure pump gas friendly. He speced the whole cam as he speced the lift , duration , LSA and gave me the recomended installed centerline. He had the cam ground for me to the specs he recomended and it has been working great for over 5 years in my eng. I have been a tech all my life and know a good bit about cams but I am no pro like Dwayne is when it comes to cams. He does it all the time everyday and every car I see with his cams in them always run great. You cant go wrong by calling and talking to Dwayne as you can call him at 802-951-1955. Good luck with it , Ron
