According to a ls forum theirs been some guys pushing 500-600 hp with a bbc that had two bolt mains.. if this is true then shouldn’t our engine be able to hold 250-300 will some solid arp studs? Plus odd number off cylinders are supposed to have less vibration due to the middle piston acting as a counter weight for the outer two. so in theory that should also help keep the mains from dancing. Correct?
