Just tossing this out. I have a mild rebuilt 400 and I'm considering switching over to a 5.9 magnum. Seeing if anyone is up for a trade the magnum would have to be intake to pan ready for an a body - carb. The 400 could come with many extras depending ????? I'm in Syracuse Indiana ZIP 46567
for a comparable 5.9 my 400 can be complete - carb to pan with headers to put in an a body ????????????????????????????????????????????????????????????????????????????
