Well the reason we did this is because everyone is always saying that you need a cobra engine to get that much horse. well apperently thats bull. i was really surprised we got that much out of it. we were running around 18-19 PSI. the block was almost fine but almost all the pistons/rods broke. the one that did survive we noticed that only 2 valves hit the suface hard, the third one barley left a mark. But yea for all the newbs that want just power and nothing else this is a good thing to look at. it takes proper/ responsible tuning to get that much horse. ill get some more pics up, and some of the other engines we are testing right now at roush.
