SC upper engine cooling tins on a 2.7?

Hi,

Wayne gives a quick mention of extra tins that were fitted on later cars and that it would be benifical to earlier cars as well. Good idea, doesnít do much or bad idea?

I picked them up pretty cheaply, so not a big deal either way.

My belief (purely my opinion) is that they were to keep the cylinder studs warmer, there fore slightly longer and less likely to pull cyl. stud threads, and when I used those on a 2.7 mag case in the eighties that is exactly what they did, prevented previous stud pulling. Not exactly a case study (pun intended) but at least one data point!

I just did it on my 2.7 1975. The tins needs a little cutting, also the others tins, you have 6 sponges not 4.
For the cooling it is an improvement, cooler heads plus warmer cylinder studs!
Body paint almost ready, so first test will be in September.
