I dyno'd both cars and both layed down exactly 424 RWHP on a Dynojet. it is true, that I have seen other 2000 plus cars coming in with numbers substantially lower than my results. My personal opinion is that the eutectic piston cars are a great starting point for a naturally aspirated build. The rods are longer and the lighter (due to a reduction in physical size) pistons lend themselves to a really responsive and powerful N/A package. If supercharging or turbocharging was your ultimate goal, then the earlier cars make for a better starting point. In the end though, if your going crazy, it really doesn't matter anyway, because a serious build will dump the stock pistons (forged or not) and step up to a properly designed per application piston.
In my case, I'm a super OCD perfectionist and I had to have a 2000 because of my color choice. Personally I feel the Vipers exhaust note sounds like the stereotype UPS truck. I knew the OEM cam and heads on all Gen II's was not going to meet my tastes. As far as why the engineers went with eutectic pistons and a slightly smaller cam on 2000 + cars.... I do believe it really was for emission purposes, specifically to meet the much tighter 2000 plus CA standards. Again, I do believe that those bleeddown lifters which actually make the cam seem smaller than it actually is, provide additional low end torque. Again this explains why these engines would perform better on a road course coming out of a corner.
Either way, this thread has been totally sidetracked, but hey it really doesn't matter because the guy who wrote it seems to have disappeared.
I'm happy Bill always jumps in to defend these cars, because the early myths started by a bunch of clowns back in the day seems to have been turned to fact, which is wrong.
