Morning Mr Kris, welcome to the forum.
if the engine turns out to be a bit sick, it’s a good excuse to go and see quarry motors and pick an engine, make it fit and have fun…. If you’re going to spend money fixing an engine, get a bigger, running one and spend the time shoehorning it in… the wife won’t know what you are doing and you can use the excuse you are saving money by fixing the old one!
enjoy!
