Hey SatngII thats a good price for machine work! I gotta move down there, up here in NYC it's alot more. Stangirl, shop around and get references before giving you engine to a shop. He's right, a performance shop will be best. You might pay a little more. But , if it's the origional motor, you dont want inexpierenced people doing the work. Dont get me started on the horror stories.
The newer mustang blocks are pretty close to spec. But the old ones are not. I just did a 70 351C and it was not even close. Have them clean it hot tanked if they have one. Bore it over, not more than .030, align hone the crank journals, and deck the block. Then everything is nice and square. New freeze plugs, and have them install the cam bearings. Have the crank done, mic'd to see if it's in spec, pollish the journals, resize the rods. new pistons(get forged if you ever intend to run a blower or N2o),
Right again, let them do the heads! When you tear it down, you can clean up the ports alittle with a grinder, but leave the rest to the pro's. If you do decide to port the heads dont go crazy in there, just smooth them out. New valves (now's the time if you want bigger valves), Hardened seats(you could get away with just the exhaust side), 3 angle valve job. The springs seals and retainers will all depend on the cam you intend to run. So will the rockers, if you want adjustable rollers, you'll need screw in studs. Do that machine work now. Once you put this together you dont want to pull it all apart agin later.
Bolting it together is fun. Read a few books on it. Engine blue printing, is one and get one on rebuilding small block fords (289's,302's and 351w's) Do you homework before buying parts, and it will all payoff. Good luck
