3.0 Engine Tin

[rwest]

I see in Wayne’s book that there is an additional section of tin that goes on top of the cylinders from 3.0 and later aluminum blocks. I see no mention of using it on a 2.7 magnesium or earlier. What are the benefits or drawbacks to using it on my 2.7?

I bought them fairly cheap, so no loss if it’s a bad idea.

Here’s a picture of the tin in question- it appears it blocks air at the middle of the cylinder where the fins are smaller.

I was going to do this same mod to my 2.7. I did not end up using the later upper baffles as the cylinder cooling tins needed to be modified to fit them. I already had my cam towers installed by that time so I didn't want to back track to make them fit. You will need the modify your 2.7 cylinder cooling tins to make them work. I was advised by another member here that it wasn't worth the time so I passed on it.

Must be a heads up issue, 3.0/3.2 use it but the turbo 3.3 does not.

Thanks for the responses, I think with your experience and the fact that Wayne doesn’t discuss using them on earlier cars that I’ll leave them off.

Best,

So just to report back, I did find the section of the book where Wayne mentions using them- he talks about the tin mods in two sections. The first section dealing with modifications says you can use them on earlier cars, so I went ahead and installed them.
