Good to hear all went well...the LS1 mods are there any internal? As i've been told 450hp is pushing the stock rods are you around that mark??there is an after market rod available through C.O.M.E. Racing good for upwards of 650+ they say all other internals are fine upto there.......???
200mph.......push baby push ...the Superformance hit a wall at 285Kmh in a wind tunnel test i believe....I'm quoting CTC
