I don't agree so much...there would be a VERY competitive Duramax, but there are some eastern trucks and Runnin' in The Red would've held it's own before he went multiple chargers, there are some Haisley and Scheid built trucks that could do it and have plenty of knowledge under their belt.
It would be a fun class, but VERY expensive, I ran a 4.1 charger at our last hook of the year, ran the same 32cm housing my buddy runs on his 680ci Big Block Deere...I couldn't believe how easy it lit, just as easy as my 3.0 Hart's Turbo, drove out at 4200 and could've done less if my tuning was smoother/ stand alone would fix it with a longer throttle throw and smoother map... I've drove my 3.0 out at 3266rpm no problem...
It would be a driver's class for sure, lol!
