86GT 93LX

the closest i can firgure out is theres supposed to be a stamp on the block where the starter bolts but theres not, its on the other side of the block and it reads e0se- a2e and so far i have found that E=80 of the decade and 0 is the exact year and S= tunderbird but this motor came out of a 1980 giah mustang. funny it would have a tbird motor of the same year! so i know mustangs didnt come with a 5.0 in 80 so i wonder if tbirds did and is this a 4.2l or a 5.0??? someone help me here

the block casting number IS near where the starter is, but its only visable from below the motor... youll have to flip it over to see it

so how do i tell if its a 302? in 80 did they put 302s in tbirds? cus they didnt offer it for mustangs. i was told they did both the 4.2 and 5.0 in 80 on the tbirds? anyone know for sure. im not putting a 255 into my stang, if its a 255 its going in my ranger

pull the goddamn intake and see. if it has uber small weenie ports is a 255. if it has normal ports its a 302

they look a lil smaller but not super small, but i have no idead if my other heads are off my 351 or a 302 that im comparing these to, usally under the intake it says 302 but this says nothing
