Hi, I have a few questions on chassis length's. Every car I've owned have all been 87/40's raised rail. Over the off season I purchased a used J&J from a guy and its a 88/41 raised rail. I know he raced mostly winged 410 shows with it and I mostly race winged 358 shows on 3/8-1/2 mile tracks. My questions are, what's the advantage/disadvantage of having a longer car.? Where is the extra inch located on the front and back of the chassis.? What radius rod lengths should I be using.? And should I been adjusting from my base setup with a longer car? if so, how? Just looking for some tips. I know everyone will have they're own opinion on the setup but just looking for a little guidance.

Thanks to everyone in advance!
