I have searched and searched and cannot find a straight answer if a series 5 t2 manifold will bolt right on with no modifications to a series 4 block. One thread I dug up talked about something needing to be grinded on the ser4 block maybe to make it fit? Another thread said it will bolt right on.

I am really pressed for time to get this engine in and am just trying to find a straight answer from someone who has done it. Will it bolt right on with no mods?

Also, I know that there will need to be some mods done to make the upper fuel rail fit. How about the fuel rail that plugs into the block? Can I use the series 4 rail, or need to use series 5 fuel rail, or modify series 4 rail?

Thanks

I don't konw about what you asked BUT I do know this:
S4 TII manifolds will fit on an S5 block with S4 fuel rails with NO modification at all.

Hmm, I would think that the reverse (s5 mani on s4 motor) would also be true then but the runners are a little bigger inside. Someone's got to know this answer.
