    1970 LT1 Fan Shroud Extension

    Can someone post a picture or describe what an original 70 LT1 fan shroud extension should look like. Is it a half circle or full circle? How wide? etc.

    Thanks,
    Dave

      It's "half-round" and ABOUT 4" wide. It's basically the same as the 69-72 big block extension except it's wider. I have one around here but I can't get at it right now.

          I beleave that is what mine are but I can't look because they are on the way to AZ. I did look at my 70/454 & they look about the same but like you said I think the LT-1'S are deeper.

                  The chances of getting a photo of that puppy with the car together from the top are slim to none. You might be able to do it with the car on a lift, but that is the only chance. I seem to remember a drawing in the AIM on the page that shows the LT1 fan shroud, but then maybe I am hallucinating again.

                      This one borrowed from Corvette Central is essentially correct:

                          That is what I was going to say it also had a rectangular notch in it but Patrick's picture post is worth a thousand words.
