Good morning everyone.

That's much to early Jay! Sounds like nap time to me!

One thing about that engine that blew Cory - if the crank journal for that cylinder is blue or black, odds are that it spun a bearing which then caused the piston to fracture if/when the bearing shells "stacked" and allowed the piston to hit the head or crank throws.. Pistons often get a bad rap because they are more fragile than the rods and pins..

Head bolts are just fine on a 302. Detonation will waste a head gasket far before head bolt failure will.

I'm sure you are well aware that the 6.0 and 6.4 were not designed by Ford but rather Navistar

Making matter worse, Ford removed so much material from the deck of the 302 that you take a big chance with hosing up the block by installing the 1/2" bolts that it should have come with from the beginning..

Also As I recall - the Navistar group placed the blame on Ford for allowing boost to come on too fast and too high. Again - exceeding the design spec of the engines.

Hello all, seems to be a lot of activity in this thread.
Not sure if this is the proper place for this, but here it is.

I am looking for a 351m/400 block for rebuilding. If it is from MCC foundry, it must have a date code later than 7C02,
which is March 02,1977

thanks
Craig
