340 or 360 Block

Hi, my 318 recent seized from letting go of a connecting rod, in need of a new block and thinking of going up a notch or two to a 340 or 360, most of my parts are salvageable so ill only need the block and rotating assembly at most. The closer to South East Pennsylvania, the better. Thank you kindly!
I have a nice 79 360 with 727 transmission. Has about 68,000 miles from a Chrysler 300. It was running good when pulled (Ohio body rust), checked and painted. It is an E-57 360, so it is a good engine that was a top-runner for 78 or 79. I kept it for a 72 Sebring Plus, but also have a 440 that will fit nicely. If interested, send me a msg... I am in NE Ohio...
