Piston Rod Shot Through Block 100k

[96 Gsx Awd]

I just bought a 2g and I have only had it for about 3k, I was driving home and I heard a loud boom. Of course the tow truck towed it home. I looked under the hood and there is a hole in the block just to the left of the dipstick. Should i just rebuild my 7bold since there is not many miles or should i build up a 6bolt and swap it in. Any seggestions would be awsome. Thanks again
