I don't think the 3V was a change for everything. I have an 05 Triton 6.8 V10 3V but the new F550's still use a 2V V10.
The 3V looks quite different from a 2V so it should be easy to tell.
With all the crap around them, I can't really tell. The valve covers are a little different, but my observation is inconclusive. I did do some homework, though, and Jared's claim that there aren't any factory 3V Vics appears to be correct. Oddly, I did find some posts from other people thinking as I, so at least I feel a
little better wallowing in my ignorant douchebaggedness.
Unfortunately, dumping a ton of money into this Vic's engine via a supercharger is just not too attractive to me now. Thousands to wind up where a warmed-over 390 can be. Where the mods shine is at the level that Cleetus is at: great flowing heads and 20 lbs of boost. It seems that an Aluminator crate with the 9.5 compression with a top-notch blower would be a killer setup, but I'm guessing you'd be in the 25k neighborhood at least with all the necessary bumper-to-bumper upgrades.
I emailed OBX about that year application thing, but nothing back yet. It appears that is an incomplete system, anyway.
Maybe we are not in the wrong hobby after all. I dunno. I'm so confused. I need a drink. Several drinks. And a lobotomy. Yep.
