People should stop reffering to the Formula Atlantic motors as 4AG's .

Sure they share a block design . It isn't a production block nor is the head . Nothing on that motor is on a productino 4AG . it's been micropolished,balanced shotpenned to the brink of God .

It's like how people called the old JGTC Supra motor's 3S-GTE's . They were 503E's a design based upon hte 3S-GTE but shared no production parts .
