Jeff,
For those of us who don't have access to that publication, can you provide us with a brief synopsis regarding 6 cylinder cars?

Thanks,

Unfortunately Bob wrote the book focusing on V8 engines only all the way back into the early 60's so no specific reference to 6 cylinders. Though some of the logic of why they were used on the V8's might apply directly to 6 cylinders. His word - " Durign 1964, generator shields (a) were used on some non-A/C engines (shown here on a 289 HiPo). Photos of original engines suggest that the shield was introduced mid-1964 production, but still not all non-A/C engines appear to have gotten them........"   Lower down he references that many engines continued to be equipped with just the slip on rear rubber boot with no larger outer shield like in the earlier years. Suggesting that it was one or the other as factory

Just sharing

What I found interesting is that all the different types of boots and covers shown so far are illustrated in the book

I think there is some debate over how accurate Bob's quote is as it seems the general population on the forum say for non A/C then it would've had been fitted with a heat shield...
When I asked the question I received the following info from a fellow forum member/admin "The general rule is that cars with A/C and K codes did not have the shield, all others did."

the two '64 gen pages in Bob's book...

Thanks for sharing!  Unfortunately, I don't think we have a definitive answer to the original poster's question.  If we take the MCA rules literally along with the other information circulating, then non a/c 6's are supposed to have a heat shield.  It seems we are having trouble finding evidence to support this.  I find it hard to believe with the quantity of 6's produced, we haven't found a bunch of original examples with a heat shield, or even 1.  I'm beginning to get the feeling the 6's never had heat shields.

It wouldn't be the first time a 6 cyl detail was overlooked in the MCA rules.  I've personally been responsible for making that error in the past... when we added the negative battery cable clamp required for 64.5 cars... only V8 had them.

But, back to O/T, it does seem like it would be something that there would be more evidence of if it was common practice.  6 cyl cars were usually in the 30-40% range of production totals.

If we're going to try and clarify the 6 cylinder generator detail I guess we should discuss if the "heat shield" is the metal and rubber fixture or if it includes the "rubber rear boot" style.   Know how detail and specific we have to get when using only words to describe this sort of detail - just a thought 


By the way changed the original posters title to clarify the focus was only the 6 cylinder

Thought the rubber boot was used on all generators, main item in question would be the metal shield.
