Which Exh. Manifolds for 360 in 65 Dart

You may also consider using a 904 rather than the 727 trans. the 727 nearly touch the floor pan. You'll have to hammer the floor seam flat. Also, where the shifter post is, may not fit under the floorpan "bump".

I'm going to install at 360/904 using a balanced flexplate and neutral TC in the 904.

also. the 727 take 50hp to turn in high gear vs. 35 or so in the 904. With modern materials, the 904 can easily take the 360 power.

I'm not sure what I"m going to do for exhaust yet. Maybe spitfires.
