Monster 4 2.6l question., Is this a route I want to take? Options

Hello and good day, please don't beat me up, i'm only asking at this point because of some things I found in my searchings. Here is the back ground as I was told, and I'm wanting you to to tell me if this is feasable or run away.
-Engine was bought complete, had low oil pressure. Race engine
-Engine completely stripped down for rebuild, crank and rods toast, needs new ones.
-106 mm cylinders and rebuilt heads to match. The heads look brand new.
-Fabulous looking duel webers. Unsure how big?
Labor won't be an issue in cost, but can this be a street drivable engine or is it just too big and will not be reliable?
Thanks,

Sorry i used the word of "race engine", I guess I can't verify that was the case. The deal is is that I'm looking at a clean case in half, all the parts except crank and rods. hell i didn't see pistons, but i did see cylinders. Heads looked brand new, but they were probably rebuilt. Sizes and all that don't know at this time except 106mm was thrown out there. If I end up with it, do i even try to rebuild it or just put it in the corner till someone comes along that wants it? last thing i need is another headache.
thanks for all your suggestions, I'm listening and learning here.
