302 or 255
So i have an engine, i believe it is a 302, but i have been told it could be a 255 which i don't want. I bought it from a friend who had it in an 83 fox body, he claims it is not the original motor, but he only owned the mustang for about 1.5 years before he sold the motor to be.
The casting code is E0AE DC3
next to it is a small place that is screwed on that read 3D8
and on the top rear behind the intake there is a partial vin that reads DHxxxxxx
So do i have a 302 or 255?

Look at the intake manifold. If it is open, requiring a valley pan, it is a 255. 302s have a solid intake, no open runners.

Edelbrock says that won't fit a 255:
Edelbrock.com - Manifolds - Ford - Performer RPM - 289/302/351W
Ports are oval, manifold might bolt up, but wouldn't work very well.

They talk about port mismatch, so it would probably, at best, run just like a 255 with 114 horse or whatever. I'd expect it to load up at idle or low rev running, as with a mismatch, you have 8 perfect spots for fuel to come out of suspension at low engine speeds.
Pull the heads, you want new gaskets anyway, and you want to look at those pistons as well.
