well back in September i bought a 75 f150 with a 360 in it, doing a moderate resto on it, and i was looking for a 390 for it, and my buddy ended up with one he got for free, he then gave it to me since he had no idea what it was. so after measuring the stroke its a 390 but i need to know a few things, the block casting says c5ae-a and the heads say c4ae-g witch are the performance heads? right? but it only has a 2 barrel intake? so if somebody could tell me what i have, it would be awesome!
thanks

My source sez for C4AE-G, 64-65 352, 390.

I'd say everyday run of the mill heads.

Possibly a '65 car engine, 9.4 compression.

It could have also been worn out three times and who knows what's inside.

Yup! Until you get into the 427 heads, all other FE heads are pretty much equal.
