NHRA STOCK CLASS DUSTER

I just wanted to to make a point for and of my friends on here who might want to race stock.
1. a 1971 carb.will make more power than a 1972 or newer carb.
2. a Dakota oil pan will make more power than a regular 318/340/360 oil pan. The Dakota pan can be put on a A-body but it may not be easy.
.
A 71 340 has more valve and more compression that the 72-73. Or does the carb itself make more power everything else being the same.

What Dakota oil pan will work on an A body?
