RE: v12 in viper
Just because an engine has more cylinders doesn't mean that it will always have more performance potential. Generally speaking, the volumetric efficiency is what makes for a good engine. The 8.3L V10 in the Viper has the potential for great volumetric efficiency (stock, it's certainly not the greatest) so why not just stick with what's in it already and improve from there.
Moving to a V12 isn't the best move necessarily. The more cylinders in an engine, the more moving parts there are. The more moving parts there are in an engine, the less reliable it tends to be. Lately, there has been a growing trend to use the "W" layout for engines with 10+ cylinders as this is far less stressful on the crankshaft of the engine as opposed to the "V" layout. One of the big reasons that GM didn't end up building the Cadillac Sixteen concept (a neat looking car with a V16 engine under the hood) was that the crankshaft couldn't reliably withstand the stress that engine put on it due to the long length of the crank and the angle of the rod movement. Talk to any Lamborghini mechanic, for instance, and he/she will tell you of all the reliability issues the V10 and V12 engines have had in their production vehicles over the years. The only big advantage of utilizing a V10+ cylinder arrangement is that, in engines of the same displacement, the weight of the pistons is decreased dramatically over that of, for instance, a V8 or V6 engine. This feature can allow for a more responsive and free revving engine whilst providing for a much smoother idle.
Bottom line is, I'd stick with the V10 that's already in the Viper. It'll be far more reliable than a V12, and cost you far less to repair/modify if the need be.

Post some pics with you and your Viper too

RE: v12 in viper
I like hardtops better, I plan on selling my convertible and getting the 2006 srt10. I just wanted the srt10 convertible so I could get used to it. Then I'll either get a supercharger or twinturbo. I don't really like posting pictures on the internet, but I' ll think about it.
