i have found that the stock ford,med riser.428 cj,pi worked so good that outside suppliers didn't even offer a replacement,until ford quit servicing them,or they were very hard to find,also we did hae a prob with the stock 390 valve sizes,lacked high,rpm pull,we would cut the exhaust to the 406/428 cj sizehelped top end but didn't lose the bottom end torque,also works great in my 4wd f 250 pickup truck |
