Nicks Garage, 572 HEMI, Here we go....

To be honest, I think more $$ than brains and some of his customers are attn seekers hoping for some "airtime" recognition.
As mentioned by several in this thread, I haven't seen Nick do much more than play with his "toy"
To me it don't look like Nick is a serious builder, from what I've seen mostly resto type builds stock muscle car may be slightly modified ones seems to be his niche and breaks it on the dyno gives it a little tune and you get a little dyno sheet to go with your probably big bill.
