i was actually thinking the same thing, i had parts and plans all picked out for a 383 small block and figured why not build a 406(had the block layin around) the 406 on a desktop dyno made more power than the 383 with the same parts. the parts i put together net a 430 horse and 525 ft lbs. i have it in a 78 gmc jimmy (6200lbs dry) the engine moves it like it a smart car....i dream what it could have done in like a GTO or any muscle car...

406 all the way
