Need to make a decision fast 5.7/6.1/340

Winter's coming...I just bought a 2013 5.7 (non MDS) with 3000kms for $1600. Figure by the time the dust has settled I should be turnkey for about 5 grand. That's TTI headers and conversion mounts, Milodon conversion pan, Holley HP ECU and harnesses, aftermarket fuel pump, etc. This engine is 395 stock. When one considers the difference in mileage between a 400 horse LA or B/RB against a Gen III Hemi, even if it costs you a bit more in the short run, it's going to pay you in spades in the long run!

My .02 for what it's worth...
