That is going to be a big cam in anything and with it's LSA it isn't going to have nice street and idle manners.

Now that I agree with.

He doesn't seem "too concerned" about the street though. lol

I'm tellin yall, I bet that is just a different version. Used to be, you could get them like that. The 528 was available at one time with both the 112 and 108 LSA, for example.

There was also a different version of the 508 small block cam ground on a different LSA.
