The reason a genIII typically is not that fast is the cars they are running in are 4500# race weight. Guys with factory 6.4s and bolt on stuff are running 12s in those 4500# beasts without ever pulling the intake or valve covers. That is not a fast time for a SB duster but try putting 1500# in your trunk and go racing and see how fast your SB is then.

Don;t get me wrong, I am still a SB guy at heart, I am still building them for me and customers but the demand is certainly slowing down and I wont get to build hot rods for a living if I don't move on. I am very excited about the upcoming trick flow SB head (wish they made it in magnum intake bolt and rocker flavor so I could bolt them on my 410 CID dakota motor but whatever), (also 1/2 my engine builds go into 94 and later dodge trucks so I think they just missed their biggest target market) but I think it is just a little late to the game. Even if it exceeds expectations it wont flow as much as an eagle head. I still just might buy a set and try to drill a magnum bolt pattern and sell my rockers to buy LA rockers, but then my cam will effectively shrink.

Also I just bought a wrecked 60,000 mile 2013 charger RT for $800 with a proven almost 400hp engine, I cant get close to that in a SB for $800, the only problem I have is the swap parts cost so stinking much VS the SB.

One disclaimer I know everyone will harp on me about but I got to be honest, there are no race tracks locally so almost all my builds are street performance oriented and only a handfull get to the tracks. I used to race when I lived in TN so I have some personal knowledge of what worked for me there, one big thing I learned is most guys are not making anywhere near what they think they are. My 400 HP 360 66 dart would keep up with or beat most "600HP" SBC cars. The stuff I have built lately would blow that old car away.
