4 speed at the strip

My dad raced a 63 max wedge with a T85 three speed (which is what the car came with)It probably had 450hp (it was a 13/1 engine) And he blew a clutch rhat punched a hole in the car he was running against about the size of a softball, and did nothing to his car. The scattershields were desinged back then to knock down debris and keep it from blowing yuor foot off. What Im trying to say is your car probably will have that much HP and I don't think I would run it without one.
