Rebuild a Intek 8hp

Hi this is my 2nd post, maybe I'll get excited and try to hit 1000 posts someday.
 
I screwed up my 8hp Intek by starting it without oil and it quit and won't run no more. That was a good motor and would start anytime down to about 10 degrees without putting a heater on it for about a half hour and that engine would split 12 inch beach even through a limb just like shaving it. The engine just quit while I was servicing it and wasn't paying attention, you know late nights after midnight. There wasn't any trashing noise other than no oil.
 
Is it worth repairing this or how would I determine what went wrong for the parts required. I really liked the way that motor ran. Its a shame to put it in a dog pile.

Thanks Roy,
My thing is that I've rebuilt automotive motors and work on my tractors and grew up in a Chevrolet shop, but never have been into small motors. What you say is correct but I was hoping on getting some pre-knowledge of what to expect. 
 
What usually goes wrong in 5 minutes of running without oil? Is it a fools errand? Is it worth the trouble and what I should expect to look for as damage and the usual parts, especially the motor casing? This was a very good engine before I screwed up.
 
The motor ran, than started sounding funny, and then started to fail and I shut it off, then realized I did not install the oil.

I don't usually have a lot of extra time, so probably this winter I will break it down for inspection and if its just throwing a new crank, connecting rod and piston on I might try that.If the case and cylinder is in good shape.  Thanks
 
Right now I'm buying a new engine for the splitter. When I blew this intek I went to get another Intek and Leigh did not sell Briggs and had these cheap Honda look-a-likes which I needed something then but I was not impressed. Now after 2 gas tanks and the shuttoff switch fell apart and the thing sounds like its going to fall apart right from when it was new, I'm putting a new engine on it.
