    71 LT-1 Engine pads

    Can any of you provide a some pictures of pad stampings on a 71 LT-1. I am looking at one and are a little sceptical of the suffix stamp.

    Thanks,

    Tim

      Hi Tim,
      Not an LT-!, but an example of a January 71 SB pad for you to compare the pad your looking at to.

        Tim, it sounds like you are concerned about the configuration of the stamp on the pad, which is really not visible in these first two photos.

        You probably need to express your concern as a question if possible (shape, spacing, alignment of characters, pad finish re broach marks, etc.) with a photo of the suspect pad, or wait for some good close-up photos of typical SB pads.

          When dealing with 1971 Corvette pads one also needs to be aware that the VIN derivative was different than those shown on early examples as outlined in the TIM&JG.

          One ugly example for your consideration

              Chuck,

              You are right. The suffix is off line with the date as well as I would like to see some more organization (straightening) in the letters from one to the other. I am trying to be real respectful of the owner. I have seen some awful pads in the past (like Terry's example)that are indeed real. The pad in question, I have no real issue with the VIN characters nor the broach marks. Naturally, it's a restored car so it raises a little more doubt. I do trust the owner in representing the car properly. But, I am the only one to protect myself.

              Thanks to all!

                Hi Terry
                The pad seems to have unusual striations, is that a factory grind-out?

                  Mike, I think we could have a significant judging school on that pad -- but to be brief I do believe it is a factory grind out. After a few adult soda pops, I would bet the discussion might get quite lively, though.

                  Gordon -- thank you for posting the 71S1xxxxx stamp. I was looking for one of those to illustrate my earlier post, but couldn't locate one in my collection. Nice pad and thanks for posting it.

                          We all know that the factory was incosistent . There must be many ways for things like this to happen .When you look at a stamp pad on a car that has had many owners ,you multiply the factor . The older the car ,more owners ,more room for doubt. How sure are you that yours is right ?
                          The N C R S uses the fact that most were a certain way and judge from that. Now you have to prove that yours is the odd one .Good luck !
