I'm still more than a little suspect of Dwayne's numbers. Look at 70 Cuda's combo compared to Dwayne's -- it has more of everything and makes only 5 HP more.
Mine ought to make 600HP, then...
You can be skeptical all you want , the math doesn't lie , other members have had their engines run on the same dyno and the numbers have been correct also . Dwayne is NOT one to fib about what he does , his business DEPENDS on being truthful .
