LT-1 hood

[Dennis D.]

Did any of the 70,71,72 LT-1s have under hood insulation?

I have been looking t LT1s for a long time, but I haven't seen them all. I am still working on that. All that said, I have never seen underhood insulation on any of them.

Terry has been at it a lot longer than I. That said, I have never seen or heard of hood insulation on C3 - LT1.

That's what I suspected. Thanks for weighing in.

But the foam on top of the radiator is another question.

Re: LT-1 hood

Yes, there is a foam barrier on the top of the radiator support frame. Not the radiator.

Absolutely Not

Re: LT-1 hood

Ron,

Not sure what your saying?

"Absolutely not" what?

Re: LT-1 hood

Jerry,

Like a lot of my judging colleagues on this DB, I am of the opinion that they did not have under hood insulation.

Re: LT-1 hood

Agreed. I thought you might have been referring to the foam seal/barrier as "Absolutely not". As I understand the foam seal is attached, with adhesive to the the top of radiator support frame. Correct?

Correct Jerome. The configuration of that seal is different depending on the year, and even build date -- but that is a whole other story.

Do we get a portion of the proceeds of this bar bet?

I'm curious what gave rise to your question Dennis.

I'm curious what gave rise to your question Dennis.

There was some discussion as to an original LT1 hood. Some mixed opinions as to big block or LT1 since there didnt appear to be bb emblem holes. I noticed studs where I thought insulation may have been. Thinking LT1 didnt use insulation

I know, alot more than you cared to know. BTW you beer is on the way

So long as we are in the "more than you wanted to know" (WTMI) camp:
Most stripped LT1 hoods show no holes for emblems, but a few have reputably been reported to have emblem holes filled by what appears to be factory processes. That falls into one of those "never say never" categories. The problem in evaluating these situations is that by the time one of us researchers gets there the evidence has usually been adulterated. Once repainted, it doesn't much matter what is underneath until the natural ageing process takes hold.

There are a few other long-term C3 LT1 enthusiasts we haven't heard from, but I am confident they will sing to the choir. I am looking forward to the brewski. Thanks for starting a very interesting thread.

I think that the hood in question is a 1969 big block hood based on the insulation retainers and the holes inside the hood.
