I just bought my first car (62 Impala) for a good project. What I need to know is where I could find some pictures of the wiring for the distributer cap. It would also be helpful to know how the cylinders are numbered on my 283. I used searches and a few sites but I cant seem to find anything. Any help would be appreciated.

or...the simple diagram.

1--2
3--4
5--6
7--8

Firing order.....18436572

The 1 cylinder is the front drivers side.
thats if you are sitting in the car, lol :p
if you are looking at the engine its:

8--7
6--5
4--3
2--1

the odd numbers being the drivers side. :thumbup:

Firing order...

Doc here::pimp:

Poncho...

Only if you live down~under where the bowl water goes Clockwise....:D Lol..:D

See, you both actually are right, If you are talking to each other and facing one another...("I said your military Right, Son...")

Like the young trainee crane operator I had working for me..."Clockwise, I said Clockwise"...looks at his digital watch and got really confused!:D

Anyways..

You are in front of the car, Looking back at the engine...

8 7
6 5
4 3
2 1

The direction of rotation will be clockwise ("I said Clockwise ,Son...") And Number 1 plug tower Will be at about the 5 O'clock position on the cap as you look down on it.

Fire order Will Be 1~8~4~3~6~5~7~2

Doc :pimp:

Could someone tell me the spark plug gaps as well? I pulled them and 2 of them were completely closed up #2 and #5. Thanks ama for the great diagram. Now just cross my fingers and hope it will start.

just for your sake the hei will fit in a 283 all u need is to clip the wire going into the points model and plug it in on the battery side of the hei the points wear out the timing and dwell move and at high rpms they bounce the firing order should be on the intake it has the same firing order as the 265 up to 400 they didnt change till the late 80's

I cleaned and reset the plug gaps and reinstalled them. I also rewired the distributor. The thing still wont start. It isnt even hitting on anything, just a small backfire out of the carb. Putting gas in the carb did not help either. I believe this is an electrical problem because it was running decent saturday before I started messing with the distributor. Time to go to the engine forum I guess.

timing

Doc here::pimp:

First, Do you have fire at the coil? 12 volts to the resistor and 6 to 9 at the coil?

Next, Fire at the points? and are they opening and closing?

Use an insulated screwdriver with the key on and open and close them you should see fire...just don't short the Screwdriver to ground while doing so or you won't see anything!

Next , Do you have Fire at the plugs? Hook up a timing light and move the inductive probe from plug to plug as you crank as close to the plug as practical, It will strobe as you crank it if you do..(much better than getting bit..)

Is the rotor actually turning when you crank it?
(maybe a broken timing chain, although it would crank badly if it was, or a broken distributor gear.)

If all that's good:



To Check your Distributer Properly, Try this:
  • Bring your #1 Cylinder up on Compression TDC.
  • Timing mark should be on TDC
  • Both intake and exhaust valves should be closed (slight play in lifters)
  • Locate #1 Plug on the cap
  • The rotor should point right to #1 plug Tower.
  • The points Should Be open, and gaped about 17 thousands..AND remember to TURN the key off BEFORE you insert the feeler gauge, or your 4 letter word Vocabulary will increase 10 fold

After you have that right, Check your Firing order.

The spark plug locations are :
  • Driver's side front is #1,
  • Passengers side front is #2:
  • IE the left side will be 1 3 5 7,
  • The right side will be 2 4 6 8.

The Stock location of #1 plug on the Cap, should be, about 5 O'clock.

Direction of rotation is Clockwise.

Firing Order is: 1 8 4 3 6 5 7 2. (see photo)

If you have this right, It should Fire right off!

Set your Timing with a light, check to see what the setting and at what rpm you need to be at for your engine, And be sure the Vacuum advance line (if so equipped) is removed and the Vacuum line is plugged while you set static timing.

Hope it Helps!

This is a "Generic Cut and Pastie I use for timing problems (so I won't have to retype it over and over..) But it applies to your 283.
