it was a joke rally get a sense of humor Walmart has them on sale I will send you a gift card

Obviously it was just that...a joke. And those numbers are impressive.

Not being a seasoned mechanic does the extra HP/TRQ in such an engine have a negative affect on the stock engine parts that were not replaced with higher performance ones over time?
