Isnt the LT5 a quad cam for the Zr1 vette? I believe aston martin helped GM design them with 4 camshafts and Gm actually had mercury marine put them in the car.

and i think the LS4 which is in the V8 impala produces 303 hp

That is exactly what it is, GM used to call it a Twin Double Overhead Cam, Two cams on each head, for 4 cams total. Gets confusing when you get too fancy with names. Correct about the LS4, looks like a typo & will fix.
