the intake is actually smaller than a stock 5.0, its more like an 86 HO intake w/ smaller ports. i think it had batch fire, is speed density and flat tappet with a different (non-HO) firing order. It probably has E6 heads and cast slightly dished pistons. It should have 19 # injectors but may have the brown tops which are 13 or 14s.
It is a roller ready block. The timing cover is probably the only thing worth having from that motor
