The things you do for family

[Jim's 72]

Sooo... My brother-in -law has a 70 Chevelle in the body shop. It is actually in the paint booth so we are expecting it in about a month( the body shop said a week so we did the math lol). He wants to run Foose Nitrous 5 in an 18/20 combo. The suspension is getting a bone stock rebuild...until the wallet recovers. When the funds allow, we will be going full air-ride with the spindles and control arms to be determined at a later date. I guess what I am getting at is, we want to run the car for the next few months before winter sets in. What is the biggest rim/ tire we can stuff under it that should work at stock height and also when we do the air-ride set up. I know there are alot of variables involved, so I am looking to eer on the safe side so we don't have to spend money twice. He is definatley more of a show-then go guy so the bigger and deeper the better lol. Again...not my car, but I better keep him happy so his sister dosen't give me a hard time lol. I know this is kinda the unanswerable without alot more info, but this is what I have to go on right now. Feel free to throw out any ideas

Thanks guys
