Stock Regal gs vs a 1996 buick riviera with a 3.4 ich pulley.

Which would win? I know the gs is lighter and would win any 1996 buick riviera s/c but what about if the riv had a 3.4 ich pulley would they be about the same? I know its a dumb question but my friend has a regal gs and he beats me by a little..and I told him wait till I get my supercharger pulley! and so I need to know if ill be able to take him when I get it.

actualy even thos the riv is a little heavier, the exhaust is less restrictive and with the gutted box and pulley you should have no probs beating a stock regal provided you get a good launch. both stock riviera and regal runs 1/4 in about 15.0 sec the regal has a bit quicker 0-60 tho. (6.6 IIRC while the riviera is like 6.9 or 7.0)

hum think I can get my riv to run in the 13's 1/4 mile?
