    Midyear NOS Sidepipe Cover #s....

    John----

    I agree with your comments about California cars(and it has nothing to do with any bias that I might have towards California since I live here). I've made exactly the same observation myself over the 43 years that I've lived here, but travelled to virtually every other part of the country(every state except Alaska). For whatever reason, California cars seem to suffer very little from rust. That isn't to say that NO California cars suffer from rust. Very often, cars which live in IMMEDIATE coastal areas, particularly along the north and central coasts, do suffer from some corrosion problems. But, the vast majority of cars seem to be virtually rust free.

    This may be due to a lot of reasons. First and formost, I believe, is the fact that California does not use salt on highways, even in the mountains. Salt is the real "killer". Often times, folks in the notheast (or southeast that drive their cars to the northeast during the summer) think that because they don't drive them in wintry conditions that they avoid the salt. Well, the salt that is applied to the roads in the winter remains there, in large measure, during the rest of the year. It doesn't "evaporate". Then, when you drive your car during a summer thunderstorm, you get the salt left there from the previous winter. Once the salt-induced corrosion begins, it proceeds inexorably. California cars do not experience this fate since, as a result of California being such a large state, few are ever driven to states where salt is used.

    Another factor, I believe, is the relatively dry climate which California is blessed with. Air heavily laden with moisture(high humidity)is another corrosion factor which California cars largely escape.

    In any event, I've always been amazed at how few rusty cars that you see in California. The contrast is a stark one when you have the opportunity to visit other states and see how many rusty cars you see. Even when you do see a rusty car in California, often it has out-of-state plates or it has a California license plate which is obviously not the car's original plate.

    This is not to say that other states don't benefit from similar climactic and road maintenence conditions. I'm sure that Arizona cars are at least as good as California cars with respect to these factors(i.e. most military and commercial aircraft are "mothballed" in Arizona for a reason). However, Arizona is not nearly as populous a state as California, so there are far fewer cars available.

    I've often thought about it in these terms: in California, the bodies and chassis of cars last a very long time, but the drivetrains do not due to the large number of miles that California cars typically are driven(i.e. it's a big state). In the east coast, the drivetrains of cars can last a long time due to the relatively fewer numbers of miles that many of the cars are driven, but the bodies and chassis rot out and spell the death of the car. Someone should take good, high mileage, rust-free California cars to the east coast and mate them with the low mileage drivetrains from low mileage, rusted out hulks. Or vice-versa.

    Re: Cylinder Heads

    Mike,

    The NCRS pocket guide says that you should have the 692's. As Joe mentioned, Tracy Performance is a good source. They have a web site, complete with inventory list of all casting numbers and dates of blocks, heads, intakes, etc.

    I spoke with them last year about a set of heads for my '60 (a mid-November assembly date) and they quoted me a price of $750-$950 a pair, ready to bolt on.

    I hunted through Hemmings and found a pair for $200 and put all new valves and springs in, as well as guides and ground the seats. Bottom line is, I spent a lot less than the price Tracy was asking.

    I live in El Paso and am in the phone book if you have any more questions.

      Midyear NOS Sidepipe Cover #s....

      I think I'll have a chance to purchase a pair of these covers tomorrow. The covers are still in the GM boxes. The date of manufacture is stamped onto the fiberglass shield, but are the part numbers, 3872283 and 3872284, stamped into the shield itself and where would they be? I forgot to check today, but I'll be seeing them again tomorrow. Thanks, Patrick

        Patrick, this may not be of any help to you but my pipes are dated 1 7 and the manufacturer was Rockwell International. It had the Rockwell Int. name and date on the inside of the insulation just a little bit before the bend in the pipe where it would turn from a pipe to a muffler piece.

        My car came stock with the N14 option and as you know they are loud. I'm waiting for one of my light weight neighbors to complain. I guess I'll have to tow my car around these tree huggers.

        Good Luck,grr#33570

          Was Rockwell International The Original Vendor?

          George, I thought that most every GM part had some kind of 7 digit number, but being that this company is not GM, maybe it didn't. Where the last NOS covers sold by GM in the 80's still made by Rockwell?

          Thanks, Patrick

              Re: Was Rockwell International The Original Vendor

              Patrick:

              Mine came with the car as it's an early Feb 67 car. They were obviously removed for several years between sitting and the car being raced because they are in excellent shape. It would seem that GM would have had a number for them for build and replace service. The Rockwell label was on the insulation only so that may have been all they provided.

              Sorry I can't answer the question about the NOS 1980 question. But I don't remember seeing any GM numbers on the covers just MFR: and date.

              Good luck,grr#33570

                George and Michael, I carefully checked both of the covers on the workbench. The fiberglass shielding on the drivers bottom is ragged, like it was sandblasted from road grit and also a couple burn marks, but that's about it. I assume the letters you are talking about are raised and not ink stenciled.

                As ratty as these covers look, I will have to assume they are original, but I don't see any numbers, but thanks for the info. Patrick

                P.S. Isn't George Michael a rock singer?

                  Side pipe rocker panel moldings?

                  I have been seeing a few sets of SP rocker panel moldings for sale on ebay the past couple of weeks. I know the pipes are currently available from GM, but who knows for how long. Does anyone know if the SP moldings are still available from GM? I know Joe probably has a few sets stashed away.

                  Thanks,

                  Bryan

                    I contacted Chevy/GM yesterday and was told that the mufflers are no more. Could it be a local thing here in Chicago? Don

                      Donald, try Eckler's corvette supply for mufflers,1-800-327-4868. I think they even have the aluminum side exhaust covers back in stock. I bought my mufflers from them last year and they had the GM logo on them.

                      Good luck,grr#33570

                        Patrick, mine didn't have the labels they have the blue stencil Rockwell Int. I just put a mirror up to the area and could see it. I wouldn't worry about any numbers if the cover or covers fit. I heard Eckler's is selling them again but I could be wrong as I haven't talked with M.Wilson or been over there in a few weeks.

                        Good luck,grr#33570

                          I just picked up the NOS Covers....

                          Got REAL lucky, I had called every Corvette Vendor in Hemmings and no one has them, all back ordered. There are not any to be had from a vendor right now. Apparently my restorer friend that sold them to me called his contact at Ecklers, who is allegedly the manufacturer of the repops, and they haven't started production yet. They have 75 pairs on backorder. And so does everyone else. Patrick

                            Patrick, Ecklers has a wall display of a passenger side aluminum cover and rocker panel but for some reason the DRIVERS sides are the sides that get damaged the most. Glad to hear you had a good day.
