Big block gears

That's a pretty short tire. You'll probably want no lower than 3.23's or it'll be howling pretty good down the interstate. I don't have a big block in my Cuda but it is a 408 so it's similar to a small big block and I'm running 3.55's with 27-1/2" tires and it's as low as I'd ever want for a cruiser. I'm thinking about swapping in some 3.23's just to see how they run cause we do a lot of cruising.
