The engine is 4.6 DOHC from a 1995 Lincoln Mark VIII, topped off with a Cobra intake. We had also installed COP's and valve covers from a 1999 Continental. I recently put in new valve cover gaskets to seal the oil out of the plug ports. I found my plug boots oil soaked and ordered new ones.
9/12/16 Well, it is time to gear up to make some performance mods. Guess I will start with another 4.6 DOHC Mark VIII engine, that I acquired during the spring, and drop some Cobra cams, springs with new gears and guides. The plan is to also degree the cams to pic up a few more ponies.
11/24/16 Update. Come to find out, if you have a 96 Mark VIII DOHC they come with beehive springs,"Go Ford !!!", I don't have to change out the springs. The cams are degreed and that took about eight hours one Saturday, that was intense. The motor is near ready to drop in.
2/15/17 The engine is in and runs out great. She has a bit more power with the Cobra cams.
1/16/18 Update. I drop in a new KKS radiator and Motorcraft RT1110 190 degree thermostat to resolve cooling issues over last summer.
