Repairing thrown rod in 1995 Chevrolet 1500

If i throw a rod and it goes throgh the oil pan only can i only replace the piston and connecting rod and be ok or not

No, If you’ve thrown a rod there is a TON of damage you can’t see unless the entire engine comes apart.

Just by a crate motor from Chevy and drop it in.

When do you plan to do this ?
