I know you can get the gt 40 heads, upper and lower intake from exploers with a 302, but what years of explorers have the 302? What about the F or E series trucks? Do any of those have GT 40 stuff in them? Do any of them have a larger mass air meter that can be used in a 5.0?

off the top of my head...

94-97.5 explorers = GT-40
97.5- '00 explorer = GT-40P

only explorers/mountaineers,lightnings and 93-95 cobras had the GT-40 heads

not much, honestly, more swirl, revised spark location, slightly higher efficiency, probably slightly smaller combustion chambers, and usually specific shorties are required, but most long tubes work.

probably within 5-10 HP of each other

easier than you'd think, the front of the head has 3 bars if GT-40, 4 if GT-40P, these are large, raised lines on the front of the head, like 2" long.

also, F77E (I think, going on memory) is casted under the GT-40P valvecover, along with the letters 'GT-40P' [Big Grin]
