Roger - hopefully you have either the SVT or ARP heavy duty oil pump drive shaft, first of all. Next, I hope the engine builder used a good moly based assembly lube to reduce chance of premature wear as well. I used at least a tube on the cam bearings - to the point I had trouble holding on to it

With a roller cam you have virtually no worry about wiping the lobes as they are steel vs a flat tappet cast iron or steel. In my case, I just primed the heck out of the engine with a primer shaft and using a variable speed drill that has 'balls' - recall that it is primed counter clockwise looking down. You will need to run that primer shaft for several minutes if the engine has never had the oil passages filled. Some say up to 30 minutes, but I do it with the valve covers off so I can see oil coming out of all the push rods. You might need to bar the engine over a couple times to obtain that oil. I then dropped the distributor back in and fired it up. Sounds like you might have a slight delay - I wouldn't worry about that. Oil - I just use the Motorcraft Semi Synthetic, 10W-30 with my 'E' roller cam and 1.7 Crane rockers. Mobil 1, Amsoil, Valvoline or similar are also good. I will NOT use Castrol - every Ford that I've tried it on will use 1 to 3 quarts between changes. The others - none. Other folks have good luck with it so I can't say it's bad oil
