Somewhere a while a back the second place finishes records were covered pretty well. I can't put my finger on the numbers right now but I have a post on it somewheres. Pretty sure you'll find that Richard Petty has the most for a single season.
Winningest drivers for the 80's and 90's
Top dog in the 80's won't even be close. Darrell Waltrip will be way out front. Next four would probably be Dale Earnhardt, Bill Elliott, Bobby Allison, and Cale Yarborough.
Top dog in the 90's would be Jeff Gordon by a fair amount. Next four are likely Dale Earnhardt, Rusty Wallace, Mark Martin, and Dale Jarrett.
