I went with the DUI in my latest build for the same reason you indicate. Seems to be a quaility piece and good customer support. Performance-wise, the DUI appears to perform well.
http://www.moparmusclemagazine.com/techa...or/viewall.htmlI've heard some small blk, A-body that firewall clearance may be an issue. Also, some big block, head, valve cover combinations may be tight too.
At the time, I also considered the MSD E-curve distributor. I've heard Pertronix are quality dist. however, I don't have any firsthand experience.
Good luck.
