what rear would you go with

Youll be slower off the line but you're Rpms songs be screamin down the road at freeway speeds. Id have that second pumpkin with the 323 in it. Besides if you opt to beat on a Chevy or ford, take it to the track and swap in the 391s. The 355 will still suck gas like the 391 but won't have that plant you in the seat type of feel to it. Even with that converter, I'd go for the 323s because you tires aren't that very big
