343 block for sale or trade, 1971 Javelin SST (missing motor) need 70-71 360 motor or selling it

I got a 343 block for sale or trade. I am looking for a 70-71 360 block for my 71 Javelin. I am even open to entertaining the possibility of selling the car. It is a 1971 Javelin SST 360 (missing the motor and radiator) 4bbl carb (have), borg-warner automatic floor shifter (all there). Original Texas car. All original. Unmolested. Still original paint and interior. Blue exterior finish with double white stripes down the side. This car has never been refinished or restored in any way! Some dummy got rid of the original 360 and was planning to put some kind of Frankenstein motor in it. I really want to build this car but, only if I can build it with the right motor in it...
