Re: Lincoln flathead V12 startup
Bill Wzorek recently sent me an original FoMoCo Repair manual for Lincoln V-12 Engines, I thought the manual would have detailed instructions as to initial start up and run in of a rebuilt V-12 however, much to my chagrin, there is no information pertaining to the start up, etc. I'd make sure the engine has oil pressure prior to actually firing it up. There's a lot of info on Flathead V8 rebuild/start ups to be found here as well as other places on the internet (Google is a good place to look), and I'm sure others on the FordBarn will offer their advice.

Re: Lincoln flathead V12 startup
With any engine you should never run them with out a load. As Vic says, make sure it has oil pressure, run for a few minutes at a fast idle to insure no BAD sounds. Put in gear and go for a ride placing as much of a load on the engine as you can. If engine is on stand, stop engine and place in car, see above.

Re: Lincoln flathead V12 startup
Typical start up on new engines: Be sure you keep the RPMs up and don't let the engine idle. This is mainly to break in the cam / lifters properly. Also want to vary the RPMs. After the engine starts, I normally turn the idle screw up on the carburetor to maintain RPMs, might start somewhere around say 1,500 RPMs. Then adjust the idle screw back and forth to vary the RPMs from maybe 1000 to 2000 every minute or so. I would have something connected to monitor RPMs, Oil Pressure and Temp. Best bet is to check with a cam manufacture for their recommended break in procedure (I'm guessing this is a stock cam, but procedures are similar for all cams).

Also, start with water only in cooling system, so if something leaks the mess is minimal!

At least you'll be able to ride in style when you go to collect your food stamps.

Re: Lincoln flathead V12 startup
id say spin it thru with plugs out to get oilpress up those have hyd lifters so they may need to "pump up" to get the lift right and not cause valve train noise when u start it

Re: Lincoln flathead V12 startup
Should have a break in zinc additive in the motor for first run. Make sure you or the machine shop has done this so you don't wipe out a cam or lifters.....even if hydraulic lifters.

Re: Lincoln flathead V12 startup
DO NOT run a V 12 with solid lifters unless it is a '36 or '37. In order to run solid lifters in the later V 12's the cam must be reground or you will wipe the lobes off the cam shaft. Rebuild the hydraulic lifters, they are quiet and trouble free if you use quality oil and change it at least every 1500 miles.
