Depends on what you need. I used their SB shorties in my Dart cause A, I didn't want long tubes and B, they are the only A body shorties that work with a 4-spd. All others are for auto only.
I've built a few big Hemi motor Cudas and they have the big *** 2.25 primary tubes.
If your just building the average street car there are plenty of other options.
I've had good luck with Hooker Super Comps and Dougs too. Hooker Comps don't fit well.
