I know there was couple more around but these are the first it floated on. Same car both.

pretty much similar to an Hemis I guess the reason why it was called the "Hemi grind"... althought the 474 is a later upgraded "Hemi" grind. The older is not symmetrical and gets 284 duration instead

What is the correct spring for the cam?

[Nacho-RT74]

pretty much the stock magnum springs

need to let you knwo the 0.050 duration of the 280/474 is not really 238 but more like 234 per some mechs real measurements. Which makes it better for driveability
