"...Under a different part number however because of the different distributor drive gear it reappeared as the 455 SD cam."
So then, I suppose you could say the 744 grind ran OK in a fairly low comp 455 ? They had originally planned to used the 041 grind cam in the SD455. I've read that it should not be used below about 9:1 CR. So, how would that have turned out ? That brings up the question, what is the minimum CR for an 041 cam in a 455 ?
Just can't help it. I love to read this Jim Hand stuff.
