Paragraph starting with Valvetrain Breakthroughs says roller lifters and cams invented in the 60's...

I only knew of mass produced rollers in 87 but I was 4 in 66 so who knew...

Yes that was iskanerian that was an aftermarket designer as was mentioned on here earlier - not GM - his engine by the numbers is a GM replacement with NO roller anything. But still a nice 327 engine that anyone would be happy with.
