Nice numbers man. When I had me stock lower end in I only have a sheet that says 435rwhp. Watch those pistons. They suck. I burnt my number 5 piston last year and i was lucky not to f my heads up too.

killer numbers!! those melted plugs are not a good sign, i think you could make those numbers safely with just a few precautions. inline fuel pump and a little race gas 
i dynoed something like 496 i think, not pump gas, not stock fuel system, not stock fuel injectors, not, not, not...... i wouldn't have thought you could pull the numbers on those stock parts and still drive it when you were done. you are crazy

Put it this way he could have taken alot of precautions very easily. For some reason he tries to hurt that dyno which isnt gonna happen! When he was just running 150 dry shot he really really hurt the stock plugs. 6 of the 8 were FUBAR! CRAZYCUTER4.8 has alot of resources for his truck and I honestly think deep down he does this somewhat stupid stuff so he can justify getting the LQ9,402,or 408 to himself and the wife! Two guys at the dyno were stunned with the numbers from that motor and a EC truck! LOL!
