Eveyone bring a gift

To start thing's off Adam I believe you are needing Ross Flat top forged piston small block Mopar 340
Part No. ros99625 Manufacturer Ross Racing Pistons
Flat top forged piston for use in 340 "A" engine block 4.070" bore size. This is .030" over standard size. For standard 340 stroke of 3.31" and stock rod length of 6.123" nominal 9.8-1 compression
I hope these will help on the 69 motor
