Check with Pete1. Forum member here. Has masters for most of the current and vintage grinds. Did my Potvin Eliminator. http://www.jalopyjournal.com/forum/member.php?u=3316
Dave has retired sad to say no more Cam Techniques he shut down operations around October of last year.
Dave and his brother Harry were neighbors when I was a kid in Stratford CT. Dave would have to be in his late 60's or early 70's and I'm sure that's why he is finally retired! KK
I'm sure Dave and his wife after so many years finally decided it was time retire plus Dave's health had not been the best for a while. During the years I have known Dave he was always willing to do a special grind for one of the many flatheads I have built. Well over 425 cams to date from Dave I thought it would never end boy was I spoiled now the search is on for another grinder that's willing to do those special orders.
