Gen 1 Vipers and 2000+ pan hold more oil than yours.
2000+ pan gasket is better
2000+ windage trey is better
Joe Dozzo does a nice baffle kit ~$350 for either your pan or 2000+ pan.
Even if you bought a 2000 pan, gasket, windage trey, and Joes baffles it is more cost effective and will hold more oil than the Mopar "ACR" ahem, pan.
