360 vs 408

I haven't ordered pistons yet. The pistons from the last engine are all trashed. I only have the fresh .030 over block, polished stock crank, cam and the heads. I haven't even had the rods checked or resized. They are still attached to the stock magnum pistons.

You make 400hp with 360 vid. That’s 1.11 hp/cid now

With a 408, very rough guess is 453 hp

With a Scat balanced rotating assy you won’t spend labor on resizing rods and new rod bolts.
