I think you are right. All Tazz had to do was mash the throttle and you would break loose. Mine are now kind of that way. I am not stacked either. I guess you can have too much HP in some cases. But in another light, the old Vipers were no different. And they were fun to try and corral. Each to their own. But if Rudy were available and closer, I probably would have been bitten by the bug. I will stay with mine for now. I guess a 10 year old car could use an updated motor in an N/A. But the electronics kind of limit your choices. But I know a Chevy V-8 has been done...and a small block Chevy will fit...So a small block Ford, some Chrysler v-8's not hemi's, although there was a hemi done... So the choices are numerous if you have the know how.
