Sr bottom end has withstood over 500hp stock, which is pushing it, but 400hp on stock sr bottom end is very reliable. Explain please, because i think you are the one needeing some education on the subject. This had 395rwhp at 22.5 PSI with no problems, only difference from then to now, is the turbo.
