ive got less then 250 horses to my s 10 wheels at the moment, and i break my 8.5'' 20's loose all the time without trying...and 'race' heads on your small block chevys are reversed, instead of going (E=exhaust, I=Intake) eiieeiie they go ieeiieei, and to run those heads you need a minimum of 110 octain, if you see him at a gas station, every, its a lie......... lets step back for just one minut here... ever go to a dirt track for races?? I do, if in case you don't, im a machanic, and a few of my buddies race late model dirt cars. These things are built with one purpous only, to go realy f***ing fast, and they, running on 110, and even the boys on alcohal, are not pushing out as many horses as this kid claims to have in his street rod. (i pushed the last perioud realy hard to end my statement with confidence)
