4.1 Timing covers

[BarnesGN]

Are all the timing covers the same for 3.8's and 4.1's?

4.1 timing covers are the same as 3.8 blocks 85 and older that have the 14 bolt pans.

Hope that helps.

14 bolt oil pans go with 14 bolt timing covers.

20 bolt 85 and up do not work.

Is this correct?

Basically yes. If you buy an aftermarket cover they have both bolt patterns. I suspect you can take a 20 bolt cover and drill 2 holes and it will fit on a 14 bolt motor although I haven't tried it. It wouldn't work the other way.

yes you can

As Neal suggest, I have drilled and tapped a 14 to use on a 20 block.

Lee,

I've really never tried to do it either way myself. So you can actually put a 14 bolt cover on a 20 bolt block eh? I figured a 20 bolt cover on a 14 bolt block would work.

Correct

My fault, I have used a 20 bolt cover on a 14 bolt block. I need to wake up!!!
