Oh dear God! 318 stroker

Yes, I am somewhat familiar with the Hughes kit for that. I sold an early 360 for a friend to a friend here and it got converted with that, a ‘68 steel 340 crank, Molnar rods, and some dome TRW pistons. That’s one I’d love to duplicate!
More just joking around on the 340 magnum (well, as a tow motor anyway). It may be feasible with a set of replacement ‘73 style low compression 340 pistons, but closed chamber heads and above deck pistons with the current head gasket availability issues (probably up to .080 thick for the Magnum 9.58 deck height) can put a project like that into eternal limbo right now…
