I have stock drums on my 69 bird, they work really well. Car has a 400 and what I think is a generic Chevy 10 bolt, at 70mph I am around 3000rpm so needless to say it’s a good cruiser. I was considering disc brake kits mainly as I put a set of American Racing wheels and with slower turns or bumps they will rub a bit and rather than rolling the fenders thought the disc kits may narrow the front track. Any ideas if this is true and any recommendations for kits
