I'm liking the looks and price of it, how much power are these speculated to hold up to?

I dunno about just how much power it will take either but with 4 bolt mains and an improved oil system I'll bet that it takes 600+ ok......

Its supposed to be able to handle 1000hp. It still requires a lot of machining like the dart blocks.

the boss block is rated at 1500hp. the motor in my sig is a boss block. it doesnt require a bunch of machining (depending on your opinion of what a lot is). for mine i just bored and honed it and checked to make sure the decks were good (they were) and that was it. it does require a special cam bearing tho. i bought them from summit (ford racing brand) for $120 and when i got them they looked like a blind man made them and then through them off the roof of a tall building. i showed my machinist and he said he could get the same bearings for $60. f*ck ford racing and there special bearings. the busted bearings went back to summit for a return

I've seen some articles on the Boss 302 block and it looks very nice. Supposedly its as good if not a bit better than both the Sportsman and R302 blocks it replaces. Cheaper than an R302 also.

it does actually all the main bores are not in alignment what so ever. the school im going to got one to build for a compition and the block had to go out for a lot of machining. its putting out 450hp n/a and then we have a 300 shot on top of that the thing is gunna be sick
