I voted some time ago but didn't really have much to say then. Gotta question, what kind of backend does the wrecker have? Mech or Hyd? I used to babysit a fleet of Chevs for my uncle when SB's were plentiful and before the time of the original "superduty". Everthing that cleared Lein with a SB got run, comp'd, tagged and yanked. Problem is today there aren't that many SB's anymore and the interchangability has went down the drain. If your vortecs don't have cracked heads, put one back together and run it. But keep your eyes open for another. Oh yea, if you running a stick behind the vortec, start hunting for a 350 flywheel. Bolt pattern is different from earlier gen and the 350 flywheel(unbalanced) is pretty tough to come by. There's alot of 305's around but they're balanced and you don't want to find out the hard way when you fire the whole thing up.
