Starting my 1963 Restoration

Hello all,
Im 17 years old and recently I have inherited my Grandpas 1963 V8 Impala 2 Door. Last summer me and him rolled it out of the garage for the first time since the early 90s and did an oil change. This restoration was supposed to be our summer project. He bought this car brand new, therefore it only had one owner. Heres where it gets interesting; this car was flooded in 2012 due to Hurricane Sandy. When I drained the oil, Im not joking when I say there was 2-3 Gallons of SALT water in the oil pan. So I figured that Ill have to drop the oil pan and figure out what Im dealing with whether I have to replace it or clean it out. Tranny fluid was as clean as can be and there is only slight corrosion around the vehicle. The water reached about half way up the wheel well so only the bottom half of the motor was in the salt water for a few hours. Also, I hooked up a battery and turned the key to see if I could get the radio working but got no response so I was thinking about replacing the harness. Overall the car is clean and was daily driven it was stored in the garage for the long run.

So, any suggestions on what I should do next or in the future? Any Ideas on what I should check or replace. Any input is extremely appreciated.

- Mike

Mike,

Here's a link to info you may find helpful:

https://gmheritagecenter.com/docs/gm...-Chevrolet.pdf

Also, recommend you purchase the '61 Shop manual and the '63 Supplement to that manual. Also, the '63 Assembly Manual is available and has tons of good info. Those documents are not expensive and are a great source of reliable info.

Good luck.

Don't replace the harness . Possibly it is good and the radio is bad. That motor will need an overhaul with salt water sitting in it

Unless you have very deep pockets full of cash, replacing parts to fix problems will prove to be frustrating and expensive. You need to learn how to diagnose the cause of each problem you encounter as you encounter the. The service manuals are very helpful in that they offered remove and replace instructions as well as diagnostic information.

Your problem will probably be found in the fuse box (where the under hood wiring harness connects to the cabin wiring harness). There is a single screw that holds the two halves together (which can loosen over time causing arcing issues), and when separated you will see lots of metal connectors that should be nice and shinny bare metal, not burnt or covered in white dull powder. Odds are they are corroded to the point where they do not make a good electrical contact.

Do you need a new harness? Only if you can not wire brush each and every contact to work again. Even then the contact at the end of the cabin harness that powers the radio may be corroded, or worse, cut off to accommodate an aftermarket Japanese stereo radio as the there wasn't an FM or stereo available from the factory back in the days of vacuum tubes. These imports used a different Ohm speaker, and tiny wires to power them; and I doubt you will find an instruction sheet or owners manual to help in diagnostics.

Thanks Dave, Ill have to open up the fuse box and check! Another thing Ive run into trouble with was identifying the engine. Of all the websites I went through, only one had the numbers I was looking for. The casting reads 3746826 and the date is B15 63 and according to the website I finally matched my numbers to, its either a 265 or a 283. How do I know which it is?

It is actually easy to tell a 265 from a 283. The 265 has no oil filter pad, and no oil filter built into the oiling system. In fact it is unique in how the engine is oiled requiring special cam bearings to reverse the engine oil down to the main bearings. So if you see an oil filter (canister or spin on) it is a 283.

The other big difference is the 265 never made it past 1958 so the side of the block is missing the three stand offs cast into every other SBC made that allows you to bolt on motor mounts. The 265 used the front and rear mounts of the 1955-'57 Shoe box Chevy (and later Corvettes).

Thanks Big Dave! It does in fact have an oil filter. Looks like its a 283. Also, in response to Japete92, I do have the 1961 and 1963 Shop Manual along with a how to rebuild your SMALL-BLOCK CHEVY book. Like I said earlier, salt water got into the oil pan and maybe a few other components so do you guys think I should lift the engine out and rebuild it? I have all the tools and say we take money out of the picture, is it worth rebuilding? Ive never rebuilt an engine however Id have no problem in trying and following along the steps.

327 was released in 1962 as people wanted the acceleration of a '57 Chevy with a 283 under the hood, but the more modern X-frame cars where much heavier requiring more power. Just like J.T. Kirk used to ask of poor Mr. Scott, his reply is the same "I'm pushing these engines as hard as I can!"

A 350 would offer more smiles per mile, a 383 more grins per trip and a 406 would have you wet you pants with joy. Just set aside the original motor for future use.

More important than the motor is keeping you and your car safe. It could burn to the ground if you installed a fully charged battery before examining your wiring and checking the circuits. You may have no brakes and your brake lines could be corroding from the inside out. Salt water is all bad. Rots any ferrous metal. In addition to the flood there is the yearly salting of the roads that the car has been exposed to. You need to look before you leap. Check the car out thoroughly.

Mike,

One way to determine your engine is by the number and suffix stamped on a pad on the front of the block near cylinder 2.

Attached is a pic of the engine that was in my '63 Impala. That number is T0425HCH. The T0425 IDs the date and place of manufacture. The HCH ID's the engine. In my case, according to the number, it was a 327 out of a '66 with a Holley carb and mated to a PowerGlide. As it sat in the car it was mated to a Saginaw 4 speed manual (wrong for '63), had a qudrajet carb (wrong for '66), and the wrong heads. But the block was a 327.

Both the engine and transmission have been replace. The engine is a crate 383 sbc, the trans is a new Autogear "muncie".

When you find your code/suffix you may find it here:

1958-65 Chevrolet full size Engine Suffix codes

If it is not yet on your list, I highly recommend the Assembly Manual.

Here's a link to some cool stuff one person did to a '64 and a sbc:

Just trying to be helpful.

You're welcome. The gentleman who made the page has been active on this forum. Perhaps he'll see that we are bragging on him and give you a thumbs up.

Your car will be different and you will make different decisions. Go slow. Learning about the car is almost as much fun as working on them. Knowledge is your friend and will help minimize your mistakes (you will make some). Good luck with your tasks.

Please share your pics. We all enjoy them.

Pete
