i dont think so,...what would you have to do to a T to get big power ?

mine was not highly tuned really, it only had the valves and rods replaced and it was genuinely ready for 400 bhp....at only 300 bhp i was barely scratching the surface ..........and if you make sure you have a newer design water pump with metal impellor you won't go far wrong , rflmao!
