Actually chubbs, I have heard someone mention offering a Viper V10 before. The problem with doing this is the current output from the Viper V10 is 510 hp & 530-535 ft-lbs of tq which is about the same hp marginally more tq than the 392 HEMI crate engine which produces 510 hp & 510 ft-lbs of tq, which weighs less, is less costly to produce, take less engine space, etc. It doesn't make sense to use this engine with this marginal tq advantage. Plus, the Viper's engine should be exclusive to the Viper in the car line-up.
