Just been busy enough to read not reply . The Hemi challenger isn’t mine it a project I have been working on for a few years . Things change in the original build but one thing I bought early on were 4 no’s 15x7 ralley wheels and although we upgraded the brakes to larger frt and rear disk they fit the 15 Ralleys .

I don’t care so much about white letters but the car owner has some strange ideas about top speed runs .... I just want the car to somewhat safe at speed . It has dynoed at 750 hp and is an all aluminum fho hemi 727 with a gear vendors and 3:23 gears it is still a 70 challenger but the real top end will be limited to the driver . If it was my car I’d go to the 17” ralleys
