Inliners International Forums General Discussion MOPAR Flatheads: how much can they take?

uncommon engineering is making 600plus HP from their blown hudson 6's.lots of mods though,to keep the bottom end together.but i think a turbo or blown flathead of 200-300 cu in should make 250-300 streetable HP without too much trouble(next project??)with around 10-20lb's of boost
