97 gmc 4x4, 4l60e and 350 vortec. Lent truck to dad. Dad didn't realize it was running hot and drove until dead. Decided to replace with a 5.3 which I purchased Tues.The 350 had a piece of the #4 piston missing and cylinder wall beyond repair. Pulled motor tonite and busted my bell housing because. Would you recomed using another 97 4l60e or getting one the same year as the 5.3. 99' model. Would my transfercase bolt to the newer trans and keep the same driveshaft lenght. Any help would be great. I have to get this truck back on the road ASAP.
