Check summit racing equipment. I know they have a kit for both the sohc and dohc motors. Their kit will only have gaskets, bearing, freeze plugs, pistons and rings. maybe some other stuff. don't expect a new crank or rods... you really don't need them any way. As for your heads, contact Sean Hyland motorsports check an issue of MM&FF for an address. Back to the bottom end. Contact a REPUTABLE machine shop in your area that does a lot of performance/race work, and get a price on balancing , machining and assembly. Unless you are running lots of boost, nitrous, or do racing only, I would go with hyperuetectic (I hope I spelled that right) pistons and not forged. Forged won't last as long, and will cause the car to use oil if you drive it before it's completely warmed up.... They are way stronger though. Hope this helps a local machine shop may have other parts sources, so will your ford dealer (parts dept.) Lots of people advertise rebuilt crate motors in MM&FF Lots of forged reciprocating assemblies (crank, rods, pistons) available there too. It's all out there, I promise!
