In case no-one has heard, Ford is bringing the Boss 302 block back with major modifications. Looks great and has some beefy ass 4 bolt mains. A full article is in MMandFF and Hot Rod makes a remark about it.
They haven't been out long enough for HP #'s but basically I think it's bringing the old A4 block back, so probably around 1,000 I'm guessing. It has water jackets in between the cylinders unlike the R302 block, which is better for street use (cooling). I still say the Dart blocks are the best out there for the money IMO...too bad I can't afford either! Haha!
