5.0's beware of FI!!!!

The 4.6 lasts so well becuase it has a lot of race technology in it. If anyone has ever worked or seen one torn down - you know why. The skirt is very deep and the main caps are actually imbedded into the block as opposed to kind of jutting out from the bottom. Also the webbing is rather thick to boot.

One of Ford's other popular strong engines was build the same way, albeit about 45 years ago. The 4-bolt 406, 427, and 428FEs had a skirted "Y-block" design and the main caps were cross-bolted through the skirts. They had small main bearings for an engine that size and boy would they rev. The dual-quad SOHC 427 made 657hp @ 7800....factory .

Anyway, from what I've seen on the 4.6s, they have four bolt mains with two more cross bolts through the block skirt for a total of 6. Is that right?
