and if you have a auto i'd put in at least a 2500 stall and around a 3.75 ratio my t-bird weighs 4100lbs and i've got a 390 with an xe-274 cam, 2800 stall, 3.82s. the cam won't be as wild in a 428 as it is in my 390 since you have more cubic inches, my power brakes work as long as i'm not in a parking lot...lol but i don't think you'll have a problem since you have a 428
