    New Member-Lots of Questions!

    Hi Guys,
    My dad and I are new to NCRS. He has had several corvettes over the years and currently has owned his 63 convertible 327/340 for about 15 years. Between the two of us we both have several collector cars of different makes and models. This car I would assess it is a driver quality car that is an older restoration prior to our ownership. This is the type of car my dad prefers because he likes to drive the car and is not concerned as much with showing the car or having it judged. I am the researcher and enjoy putting cars back to factory spec. This is what drew me to NCRS when I began to do some work on his car for him. After getting the shop manual, assembly manual, and a collectors originality book to check the history of the car, I have now become interested in making his car as correct as possible. After rebuilding the carburetor I noticed it is a Carter AFB but the numbers would have it as correct for a 1964 car. Is there any difference other than the number on the Carter AFB's between 63 and 64?
    According the my material the tags under the glove box the car is an early production car. It has the compartments behind the seats and the early 63 side mirror. After inspecting the block, I can make out the engine code denoting a 327/340 but when the engine bay was detailed by the previous owner the pad was painted over and as was the entire intake manifold when the engine was painted the factory orange color. According to my research and other cars at shows the intake should be unpainted or silver? The other numbers on the block appear to "match" the other numbers and the date and plant that it was cast for this cars build date. I have yet to check the chassis number but will try to take off the rear wheel and look this weekend with a mirror. I have read that this is the easiest way to verify this number? Another question I have is how to determine the axle ratio? The casting of the rear differential reads "Muskegon Brake" I believe. I look forward to being part of the board and getting help maintaining and restoring my dad's car. I will try to post more details about the car as I go through it. I am currently replacing the gas tank due to a leak in the current tank.
    Thanks

    Justin,

    Welcome to the NCRS! I can't comment on very much of your post, but I would think that the engine pad should be unpainted. If you haven't already, I would suggest getting the Technical Information and Judging Guide from the NCRS store. It will have a wealth of info on your car.

    If you desire to remove the paint from the pad, here's a good thread on the topic:

      Hey Justin !!!!!

      Welcome to the NCRS !!! Just get a little paint stripper and apply it to the engine pad with a brush. Let it sit a bit and then wipe the paint away. We should be able to confirm the 340HP and matching numbers for you at that point. You are correct that the intake of a 340 HP car should be aluminum and not orange.

      The code for the differential will be located on the flat surface on the bottom flange of the gear case.

      63's are very unique and a ton of fun to study. Post up some photos of the old car and start asking questions !!! I'll be glad to try and help and I'm sure everyone else will to !

          Thanks for the tip and responses guys. I will try to post some pictures and numbers from the car this weekend.
          Thanks

            The casting of the rear differential reads "Muskegon Brake" I believe.

            Brian, this piece is the "heavy duty" replacement piece sold by Muskegon Brake, not original to the car. Many replace the originals with this piece when the original cracks, often around the bolt holes at the spring mount. There are some previous posts identifying how to calculate the diff. ratio. If you can't locate let us know.

            Welcome to you and your dad! There is more knowledge on this board than you can imagine, as you have already seen.

                I just ordered the "Shipping Data Report". Our VIN is 30867S101784. This appears to be a very early "63".

                  Re: New Member-Lots of Questions!

                  Be careful when assessing individual components needed for proper restoration based on 'early' vs. 'late' distinction.

                  Once the factory started production of a given model year vehicle, there were running changes made here/there. The parts used are generically referred to as 'early' vs. 'late'. But, the distinction applies on a PART BY PART basis dictated by WHEN that particular running change was made.

                  So, early/late for one component might be around the VIN 2300 range while the early/late cross-over for another component might be at the VIN 28000 point! You determine this by reading what's textually described in the Judging Guide (JG) book. AND, you can often get a 'feel' for what's right by looking at the Assembly Instruction Manual (AIM).

                  Go to the AIM page where that part is called out for installation. See if the part is 'flagged' with a footnote and then look at the ECR block at the bottom of the AIM page. It generally, provides the information on part running change (A -> B) and the date that particular change was authorized.

                  Understand, when you interpret this way, you have to cut some slack as to the effective date. Why? In most cases the factory didn't run out, gather the old parts that were still in inventory and SCARP them. They typically used up what was in the system resulting in mixed usage on the assy line until the first generation part was completely flushed out of the system. That can mean MONTHS of continued use depending on what the inventory balance was at the time of change...

                    Re: New Member-Lots of Questions!

                    Jack is giving you good advice. My 63 was built late October so for most items it is usually considered an "Early" car. It does however just fall into the VIN range for the later version wheel covers. Was probably one of the first few built with those covers but for that item in particular it could be called a "Late" car.

                    If you are looking at anything expensive or had to get and are not sure if it is correct ask here. It is the best place to start.

Paint can be chemically stripped with Aircraft grade paint stripper and a stiff nylon brush followed by a lacquer thinner wash. The intake on a 340 hp car should be bare aluminum. You should remove it from the car before you attempt to strip it. Please do not bead blast it as this will ruin the cast finish.

                      ...I have yet to check the chassis number but will try to take off the rear wheel and look this weekend with a mirror. I have read that this is the easiest way to verify this number? The VIN derivitive stamp on the frame kick-up can be seen on top of the frame in the left rear wheel well, just slightly forward of the rear axle. Sometimes a small mirror is helpful.

                      ...Another question I have is how to determine the axle ratio? The casting of the rear differential reads "Muskegon Brake" I believe. The code for gear ratio and assembly date will be stamped on the bottom flange of the main case. Sounds like you have a replacement cover from Muskegon Brake. The main case and gears may very well be original.

                            Hi Justin,

                            Here is a pic of my stamping on the bottom of the rear case. Look for more numbers on yours. The ratio code will be letters.

                            CA = 3.08
                            CB = 3.36
                            CC = 3.55
                            CD = 3.73
                            CE = 4.11
                            CF = 4.56

                            The numbers represent the assembly date. I suspect your case was assembled on the 18th of some month.
