Power adder is where it is these days. I am happy with my Hemi on the street cruisinaroundon motor. The neighbors and the general public may not be, but I am. Then just spray the snot out of it at the track.
I am kinda thinking that way...My engine builder has a newly built 440/543 with TF270 heads on it he offered to me. Its low enough compression to put a Torque Storm on it. With my 3.73 gears and the mild manners, I think it would still make the same HP & Torque as the big Hemi.
