The Renteria's Valiant is truely a bad A$$ racecar. If you all have ever seen it in person it is a gorgeous car. As for the perfomance given the weight they run and the small engine and blower(451 cubes and a 6-71 blower)the car is truely impressive, 6.60's is very very impressive.
For those who have not seen it here is a link to a nice video of the car
