351 windsor swap
 

Anyone have any ideas on how to swap a 4 cyl. to a 351 windsor in a 78' stang'II, the engine is a 79' 351 windor??

I don't know how hard it will be. The 302 came stock in the 1975-1978 Mustang II's. It had all of about 1/2" clearance on the passenger side, and 1 1/2" on the drivers side. It ran standard exhaust manifolds, I would think the 351 would wind up being a little harder to fit in there, but I'm not super sure. You may need to bang the inner fender a little to get it to fit.
