That seems about right for a stock LS..from what i understand the ls motor is great for boosting, but search honda tech and this site for more info on boost setups, i think the stock block can go up to about 225-250 hp on stock rods? once again i could be mistaken.
stock? idk...the rods are thicker on an LS but not by thattt much...ive heard b series motors can handle around 300whp.....
