I've got a 440 in my 69' Cuda and was happy for many many years with my 2" hooker fenderwells but the biggest sacrifice was front tire size. Just got talked and talked myself into the chassis exit 1 3/4 TTI's just so I could get a bigger front tire. Got rid of the KH brakes and upgraded to the later Single piston jobbers.. Just mocked it up this wknd and phew its a tight one.
