    I'm still trying to figure out for sure what engine I have. I'd like to build it someday and maybe put it in one of the Mavericks. I think I'd back off the EFI and go with a carb setup. Anyway, if I knew what I had, I could be watching and gathering parts.

    This is what I do know:

    It's an '80's something EFI engine.

    I'd like to know if it's a Windsor or Cleveland. Can you still put 351 heads on a 302 of this vintage?

    Attached is an engine pic and one of a tag I found, is there something else I need to look for (another tag someplace)?

    Thanks for any help you can offer....

    intake says its a 302, but they have two parts. Although I think you can put a 302 upper on the lower 351w, not real sure though as Im not in to EFI. 99% a 302

    Yup, that is a 302. which is known as the 5.0 liter.

    As far as putting 351 heads on a 302... yes they are the same.

    But technically, a 351 head would hurt it more than a 302 head. The myth of a "bigger head" on a smaller motor making more power isn't true.

    The 351W heads would be good if...they are pre74...small chamber/big valves.After 74 the chambers got huge on the 351 heads and valve sizes dropped to 302 sizes.

    I wasn't sure on the year. Thanks for informing me.

    I knew the newer 351 heads aren't worth using IMO

    If you get a picture from the front of the engine that shows how wide the lower intake is, we can know for sure if it is a 302 or 351. 302's have a very narrow intake. It is definitely of the Windsor family, though, just looking at the valve cover.

    I disagree, look at real Boss 302 heads and 4V cleveland heads (even the 2V's are much larger than any windsor port). They will walk all over 302 and 351 Weezer heads and the ports are significantly larger (and no, they aren't dogs on the low end).

    I don't think I would put standard 351 W heads on a 302 unless they are the aluminum GT-40's and it's a low buck build.

    It's a matter of how efficient the port is. Volume vs cross sectional area and velocity...

    that is a 1986 standard non ho 5.0 out of a t-bird or cougar

    that style upper intake will not bolt on a 351 lower intake

    Ditto on the 351 upper intake not fitting a 302. And it could have also come from an LTD, Merc Marquis, or Lincoln Towncar. 150 hp. The heads suck. But to be sure, check the lower front corner of the passenger side head, just outside the valve cover. There' you will find either an "S" or a "T" The "S" denotes The crappy E6SE heads, the "T" will be E7TE's. If it's got the "S" heads, it also will not have valve reliefs in the pistons, so that will limit your choices in performance parts like heads and cams. On the plus side it will be a roller block with a roller cam, just won't be the HO roller in it. It'll be the smaller "base" roller.

    That intake is wrong for a Panther car, my guess is that it's out of an '86 Thunderbird. With new pistons, the short block is as good as any other. I'd bet money it's got E6 heads. No promises, but it SHOULD be a roller.

    If you don't want to tear into the bottom end, then just stick a B303 cam in it, some ported E7's and a 4v intake and carb on, and it'll run pretty good.
