318 Threw a Rod

I have a 1968 Alglas with 318. Long story short I had a marina remove the engine to replace the mounts do make an alignment repair involving a new strut etc to fix a vibration problem. $4800 bucks!!!!!!

They said they ran it on sea trial for 5 miles. I put about 2.5 - 3 miles on it and it blew a rod out of the oil pan.

Not good. Lots of noise and smoke.

So my questions are....
What is the max angle a 318 can sit in the boat? Is there a preferred range?
How is amount of oil determined? IE does the angle affect the amount needed so it says full on dip stick? If marina did not properly adjust the oil to reflect the new angle of the engine could this have caused my blow up?

Any help would be appriciated and if any body knows of a 318 I can get my hands on in the Delaware/Maryland/ New Jersey area send me a lead.

Without changing the position of your stern tube as well, I doubt you could angle the engine enough to make that much of a difference and still be in alignment. I think you have to look elsewhere for the failure; fuel, timing, age, maintenance history, etc.
 
It would seem that the only angle extreme enough to cause oil starvation would occur when the boat is getting up on a plane and held in that position for a very long period.. A few degrees of alignment wouldn't seem to be a problem. Automobiles using this engine are sometimes subject to some severe uphill and downhill angles and don't seem to have a problem. Was there oil pressure when you got the boat back from the repair and was there oil pressure before the rod blew?
