So I'm faced with several decisions on which direction to go with overhauling in frame or engine swap for our 1972 58' Yachtfisherman.
Yes, I am well aware of the size and scope of the project. No I will not hire a "professional" to do the job as I have no need since I can do most of the work myself while having access to many friends in the overhaul industry for technical guidance .

My main discussion questions are mainly to those that have done "in frame" overhauls and to those that have done engine out swaps. This experience is very valuable to me. Any thoughts, tips and ideas would be greatly appreciated!

Not to be overlooked, I have contemplated the idea of perhaps going to a newer engine (cummins/CAT) but obviously the costs are vastly different and perhaps prohibitive.

So let's here the pros and cons, the experiences and the do's and don'ts.
