Not really. You'd potentially gain a little bit in the 1/4mi and a bit of feel, but since your not drastically raising the powerband, the converter won't net you nearly what it would on a more aggressive setup. The LS6 gets brought up in literal cam-only discussion for that reason.

If you want to spend the 5-900 on a 'verter, its still a good purchase....however if you decide to go bigger on power in a year or two, you might need to re-spec the converter (and that is no fun for the back, or the back pocket).
