TT 5.7 hemi in 75 duster

His build is ambitious? or the power suggestion?

Well, both. I haven't heard of 25-30lbs of boost on a new Hemi. A 6.1 based TT 426" a friend built is looking at 8lbs of boost in the 800hp range.

I dont know much about the chassis build, but supporting 1000hp+ isnt easy or cheap
