Interesting, since I'm considering running one behind a 5.7 in my Sweptline. Mostly because I have one, and NV4500s are priced too crazy around here- even 3500s are fetching an arm and a leg it seems.
I'm running a 5.9 Mag in front of my Dakota's NV2500 (original 4 cyl. trans) so far with good luck, the AX15 was going to be my spare for this rig, but the Sweptline is calling me...
