    .....my 415 small block Chev. puts out 499 ft/lbs @4000 rpm & 438 hp @ 5250 rpm. I got an engine kit with a 4 bolt main but the machine shop found something wrong with the block. When I went back to exchange the block all they had in stock were 2 bolt main blocks. The professional engine builder who built my motor said that a 2 bolt main block would be just fine for the hp & tq that my motor would be putting out. He also said that running high RPM's was what would kill a motor that at my RPM levels I would be fine. So I just went with the 2 bolt main block.... Bill......
