Tires / diff ratio advise

Did you dyno the engine? How do you know where it builds power? If it's based off the powerband on the cam card you might as well throw it in the garbage, most often TOTALLY inaccurate.


3.55 and 15" wheels with 27 - 28" tires is a no brainer.

The engine has not been on a dyno. Just using the cam as a guide.
I do like the 355s and 15" wheels. Just figured I'd ask and see if there was something else to consider. I am going to order the gear set soon. US gear is what I am leaning towards. Thanks
