I would find out what it cost to rebuild it locally.
Could even find some vortec heads and have them installed while your at it

I was thinking about going that route, to upgrade to that I would just need to change the manifolds? I would just need to know what all I would need to purchase to make the vortec work, because the boat may not be worth putting all that money into

Your old manifolds will work with vortec or non-vortec, no issues

The heads are what make a motor vortec. Newer blocks can have some added advantages but not enough that would change to get a newer block

If you find a good truck motor with low mileage that would be best, but even a higher mileage motor (not more than 100K) could still be ok if compression test out

I'm not finding anything local with under 150k. There's some across the country I requested quotes on , under 100k miles, only a few that don't want more than reman
Also been searching a bunch of rebuilders for a reman. Alot of them had poor reviews, but a company called "powertrain products" . Leaning towards reman. So shopping that while I await quotes on yard engines.
