Already running the victor knock offs, haven`t got it broke in yet, still refining little things. (7yr build) I can tell u that what little I`ve played w/ it, it has me greatly anticipating a dragstrip run, it really wants to get w/ the program when the converter locks up. Haven`t had it over 5000 rpm yet. A t this point I just want it to stay together, getting too old for hard line mechanix. feels like it`s going to have an unbelievable top end.
