I am running stock exhaust manifolds on the 401. I ran outside the frame side exit headers on the original 304 for years. That and too mant .44 mag's touched off with no hearing protection account for my hearing loss.

Let's see some inside the frame rear exit headers.

This thread is dealing with all AMC V8 engines. The 304, 360, 401 and the older AMC engines are all the same size externally. Go back to the first page of this thread and it should answer most of your questions.

You can re-use the rubber mounts you already have from the I6 (if yours are in crappy condition you might want to replace them.). You need both uppers and only the passenger side lower you can reuse the drivers side. I don't know which is considered left or right

Also I'm assuming that the "lower" mount means frame mount and "upper" means block bracket.

I've circled the needed parts for you:

Can someone verify that the drivers side frame mount is the small one? Its been a while since I did my swap and I'm not 100% on that.

You need all of the mounts and brackets in the picture except the small frame side mount (driver's side). It is the same for the 258 or V8's. The rubber motor mounts are not the same for the 258 and AMC V8's. Full size Jeeps and CJ's use the same rubber motor mounts for AMC V8's.

Really? I could have sworn I used the same ones from the I6 before I used the M.O.R.E. thanks for clearing that up

Yeah, the factory V8 mounts have a diagonal bolt pattern and the 258 has only one bolt I think. Other than that they look the same.

304 heads have smaller valves. Look for dog leg heads from a 360 or a 401.

I hate to do this, but there is something not quite right about the old 360/304 flexplate thing. I researched this subject a lot, (about a year ago) and I never could get a definite answer. I currently run a 304 w/ a TF727. The flexplate I ordered is for a 360. (because I have a 360 to swap in one day) I don't have any balance issues from the motor. Should I. And forgive me if I have misread something somewhere, but this subject is very confusing especially if you ask more than one person.
