What engine do I have???
I picked up an 86 GT mustang with a newer engine dropped in it. The problem is, I don't know what engine it is and neither does the guy I bought it from. How can I determine this??
I found a number under the valve cover on the drivers side "F1SE-BB (or 88)" but this doesn't seem to match up to a Ford service number but I believe the F1SE means its' a 91 Thunderbird engine. I'd like to verify this and to verify whether this is an HO 5.0 or not. The intake manifold does say it's a HO but for all I know the intake manifold or even the label plate don't really go with the engine.
Any help would be greatly appreciated.
