408 roller cam?

Looks like a fuel injection cam. Or NOS?
The CNC Speed master heads are pretty OK for a OOTB head and will take just a little work to get more cfm out of them on the common wall in the back at the bolt bulge, etc…

Why a dual plane?
I guess I’ll have to through some nitrous to it. The dual plane I already have. I thought with the dual plane and 4:56 it wouldn’t be such a dog out the hole, coupled with the 904 low gear set it probably should help it wouldn’t it? Clearly, I just buy random **** and through it together. I don’t know what the hell I’m doing? Haha I’m learning.
