Mike, i've got moroso drag specials in 7.10x15 on the front of the valiant. To make them fit you gotta either run a 3.5" front rim with 2.25 backspace, or trim the wheel lips... I did the latter...
I like the 67 hemi scoop fastmop has on his car, but i don't think it has anymore clearance than my MW scoop. I'm not sure if i'll have enough clearance with my current hood and my W8 motor...
