365 or 408?
you still need to have the stroker pre-balanced kit checked over
some of the journals on the scat & eagle cranks are not perfect due to bad q/a at manufacturing ... sometimes the cutters get dull so the crank journals are not square at the edges, etc.
also balancing is only $150 or so.
the money you will be saving is for the new pistons. ~$300
but the stroker kit needs to be clearanced at the bottom to make sure your rods dont touch the block anywhere, etc. also you will need a different windage tray because of the stroke.
so really you are not going to be saving anything. just add about $2000 when all is said and done, if you get a good deal.
