Really stupid question, is the 302 block the same no matter what car or truck it comes out of? My dad is giving me a crappy van with a 302 in it but it just needs to be rebuilt because the head gasket went on one side and sat for a little while. I would be able to take that engine out clean it all up and put into the mustang just as long as I put the right motor mounts and other parts on it right? or no
Far from it. Since about 64 or whenever the year they were introduced there have been a whole slew of different versions, like block revisions and a whole army of head revisions, intake changes and so on. Then you've got roller and non roller 302s, plus HO and non-HO motors. I'd find out what year the van is and you can sort of go from there.
It's a 1990 E-150 van with a 302, what I mean is the block it's self completely empty would I be able to take that and rebuild it with all the parts i want with it and put it into my mustang?
Again that depends on a few things. If it's a bare block, and i mean BARE, then the first thing would be if it's a roller or non roller block. By '90 they should have all been rollers, but in a van i couldn't tell ya for sure.
You can try these heads: http://performance.drivewire.com/enginecomponents/forde-150econolinecylinderhead.html If not, Wikipedia says 75-91 ecolines did come with a Windsor V8 http://en.wikipedia.org/wiki/Ford_E-Series So, if it's a 1990, obviously I'm not for sure, but I'd be willing to bet it's the same block as a 1990 Mustang.
Alright thanks for the help guys, I'm going to try to pull it out of the van next week i got most of the engine apart and take it from there. Thanks again for the input!
