cam shaft 284/484 and new lifters

Big or small block?
from small block 360! I got my 360 engine when I bought car the Duster and the engine had just been rebuilt but I wanted to go with a roller engine so these parts were removed from engine
Are the pistons a weight matched set? I wish you would price them.Your inbox is full.
Sorry about no price but I was only going to advertise cam and lifters but ended up posting all the parts I would like to get $225.00 + shipping for pistons, rings and wrist pins! The pistons were already in my "rebuilt" never ran engine when I bought my Duster so I am not sure if they are but do not know why they would not be. I do not have a scale. these parts were removed from engine because I wanted to go with roller cam and lifters and different pistons!
