You can use whatever you want but remember it is an oiling system not a grease system. The clearances are sized to flow oil not grease. On the 351 Windsor they had used what I would say was a liberal amount of white grease and on that engine the oil comes into the main bearing, enters the slot, and then travels over to the hole that feeds the cam bearing. I think what happened was they put grease on the bearings and then put the crank in place. This pushed the grease up into the cam bearing feed hole. When the engine started it starved that bearing of oil because 60psi of pressure isn't enough to force grease up through the hole and out through the bearing clearances. Probably what happens a lot of the time with grease is that the engine starts and runs with no oil flow to the bearings until the grease gets hot enough and soft enough to get forced out.
I think that it would be much better being put together dry than with grease. Then crank up oil pressure by hand before starting the engine to get oil to everything.
