As I believe we already told you, the LT4 manifold is almost completely identical to the LT1 manifold. Difference is a little extra material above the intake port at the head flange.

GM put 28# injectors in the C4 LT4's, and the LT4 didn't include the HOT cam. If you are approaching 400 flywheelHP, the 28 #/HR injectors, or larger make sense. You can "get by" with the stock 24's at that level, but the duty cycle will be above the normally recommended upper limit.
