Be careful- - - - -when a cam grinder caters to racers, he tends to recommend stuff that's far too radical for the street. It's the old "I've got a big hammer, so everything looks like a nail" situation. It really is possible to make a silk purse from a sow's ear, but it makes the pigs look funny and they don't hear very well. The tech rep at Elgin I talked to said they used a GM factory cam for a 261 as a pattern, and duplicated it exactly.
