X heads on a 340 HP potential???

I like it , numbers speak for themselves 412 hp 398 torque . Have just about the same set up , heads done just like yours by a real mopar guru . He's been doing mopars for over 35 years . Was thinking of going with the 60404 , but not with an auto and the converter I have , with a 4 speed maybe .
Combo works well , everybody was pleased with the numbers it pulled on the dyno . Pulls well at any speed , punch it at 20 and it will smoke the tires , punch it at 60 and your hitting jail illegal in no time .
