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.
