yo RYAN,
Identification, 5.0 & 5.8
To determine which EFI V-8 engine you have, look closely at the EGR Tube;
The 5.0L EGR Tube runs from the lower intake manifold to bottom of EGR Valve
======
The 5.8L EGR Tube runs from the passenger exhaust manifold to bottom of EGR Valve
==========
Identification, 5.0 & 5.8; "...quick ID tip: The lower thermostat housing bolt on the 302 will be below the top of the water pump and you won't be able to put a socket on it. On the 351W you can remove the bolt with a socket.
The positive ID is to measure the lower intake; 302 is aprox ~ 8 inches wide. 351 is aporx ~ 11 inches wide.
The 5.0L uses squared ports and the 5.8L uses oval ports. If you get an intake from a junk yard it will have the matching fuel rail..." Read More

Carbed Engines:
Windsor/Cleveland engines. "...The most obvious external difference is the engine valve covers. The 351W (Windsor) valve covers are attached with 6 bolts, straight front to rear, and narrow in width (similar to the 302 c.i. engine.)* The 351C (Cleveland) valve covers are attached with 8 bolts, flat with 2 different planes, and wider in width. The 351W engine has a radiator hose that attaches to the intake manifold, while the 351C attaches to the engine block. (See Graphic 1 on next page). The 351W takes a 5/8” thread spark plug and the 351C takes a 14mm thread plug. (See Graphic 2 on next page). Distributor differences: The 351W has a smaller 1.245” diameter distributor gear, and the 351C has a larger 1.418” diameter distributor gear. Each engine has a 5/16” oil drive at the bottom of the shaft and a 1.557” diameter housing, measuring directly above or below the O-ring area. *The Ford 302 c.i. engine has a ¼” oil drive on the shaft, a small 1.245” diameter gear, and a smaller 1.550” diameter housing. Windsor 351 V-8 Engine: 1. Valve cover is held in place by 6 bolts. 2. Radiator hose connects to water neck on.." The 351 Cleveland's radiator hose attaches to the radiator and connects directly into the front of the engine block. It makes a 90° bend from the radiator to the engine block.Cleveland 351 V-8 Engine:1. Valve cover is held in place by 8 bolts. 2. Radiator hose is a 90° hose that connects directly to the top front of the engine block..." see diagrams
