Help With Identification And Bits Of Distributor I.d. Info

Thanks, Grumpy. It's not mine or for sale. Unless you want the whole car. He might sell it.

I can't find what the DJ is in any of the links. Any Idea?

v06191dj
 
Ive looked in several placces, DJ comes back as a 283, but the block number prevents a match
 
well thats conclusive in verifying the engine displacement,
but you know the block was originally a 4" bore, if thats the original casting number,
so depending on the stroke it could be anything from a 302-383 rather easily.
keep in mind thats assuming the block pad stamp is original, which it may not be.
(its harder but certainly not impossible to change casting numbers)


Chevy V8 bore & stroke chart
I saw this online and figured I would post it..I am going to add the popular lsx strokers soon
CID BORE STROKE
262 = 3.671" x 3.10" (Gen. I, 5.7" rod)
265 = 3.750" x 3.00" ('55-'57 Gen.I, 5.7" rod)
265 = 3.750" x 3.00" ('94-'96 Gen.II, 4.3 liter V-8 "L99", 5.94" rod)
267 = 3.500" x 3.48" (Gen.I, 5.7" rod)
283 = 3.875" x 3.00" (Gen.I, 5.7" rod)
293 = 3.779" x 3.27" ('99-later, Gen.III, "LR4" 4.8 Liter Vortec, 6.278" rod)
302 = 4.000" x 3.00" (Gen.I, 5.7" rod)
305 = 3.736" x 3.48" (Gen.I, 5.7" rod)
307 = 3.875" x 3.25" (Gen.I, 5.7" rod)
325 = 3.779" x 3.622" ('99-later, Gen.III, "LM7", "LS4 front wheel drive V-8" 5.3 Liter Vortec, 6.098" rod)
327 = 4.000" x 3.25" (Gen.I, 5.7" rod)
345 = 3.893" x 3.622" ('97-later, Gen.III, "LS1", 6.098" rod)
350 = 4.000" x 3.48" (Gen.I, 5.7" rod)
350 = 4.000" x 3.48" ('96-'01, Gen. I, Vortec, 5.7" rod)
350 = 3.900" x 3.66" ('89-'95, "LT5", in "ZR1" Corvette 32-valve DOHC, 5.74" rod)

400 = 4.125" x 3.75" (Gen.I, 5.565" rod)
427 = 4.125" x 4.00" (2006 Gen.IV, LS7 SBC, titanium rods)

Two common, non-factory smallblock combinations:

377 = 4.155" x 3.48" (5.7" or 6.00" rod)
400 block and a 350 crank with "spacer" main bearings
383 = 4.030" x 3.75" (5.565" or 5.7" or 6.0" rod)
350 block and a 400 crank, main bearing crank journals
cut to 350 size
 
I must have missed that link,
yes the block casting number was used for the 350 SBC,
please post a reference link
the only similar info I see..

Chevy made more than a million of the 3970010 blocks between 69 and into the ‘80’s(Corvettes stopped in 1980). We know it’s not a late block because half way into ‘77, GM started for ‘78 making the stamping pad square and the stamping very straight. And only a few “. . . . . . 010” castings were made for the 1969 Z/28s. The 283 as mentioned - not possible.
The OP’s is likely over the counter stock, restamped at a rebuilder’s shop or a marine motor. That goofy looking “SP” stamp is likely someone tagging their ownership as some speed shops and others have done in the past.
 
Distributor
Distributors from 1964 through 1966 were generally cast iron while 1967 and later were aluminum. 1964 through 1966 units have a codes embossed on an aluminum band while the 1967 and later units have the codes stamped into the housing.

id_bands.jpg


The date code on a distributor is simple to decode. It includes the year, month and day such as 7K25. This decodes to 1967, October, 25th. Month codes are A through M for January through December (omitting 'I').

One astute reader has measured the outside diameter of several original distributors. The main body where numbers and dates are stamped is about 3.810-inches. For about 0.200-inches down from the distributor cap mount the diameter is about 3.795-inches. If the main body has been turned to allow for new numbers to be stamped, it should be easy to tell if this area has a smaller diameter than 3.810-inches.

A - January B - February C - March D - April
E - May F - June G - July H - August
J - September K - October L - November M - December

General Motor’s HEI distributors are still going strong.

GM’s High energy ignition (HEI), designed and built by the Delco-Remy division of General Motors starting in 1974. These units were used on all engines in 1975 through the mid-1980s, with several different variations over the years. Characterized by the incorporation of the ignition coil built into the distributor cap which eliminated the need for a coil wire.

The system consists of a control module and a magnetic pickup inside the distributor housing which removed the ignition points and condenser. The control module basically performs the same function as the breaker points in a points and condenser system.

Within the General Motors supply system, the choice in HEI system type was important based on the engine that it was used in. Each GM division had its own engine design so a Chevrolet distributor would not fit on an Oldsmobile, Pontiac, Buick, or Cadillac engine or visa-versa.





While the distributors may look alike, the parts inside are not alike especially in terms of the ignition coils and the pickup coils. Ignition coils and pickup coils should be considered a matched set. Look at the color codes on each part and match the codes to each other, and to the vehicle/engine family the distributor will be used in. Failure to use the appropriate color codes may result in poor starting and misfiring at low speed.


Color codes must match from the pickups to the engine/vehicle.

The control module type is important as well. The control module is the heart of the HEI system. There were three basic types of HEI control modules. The four-pin control module unit, which was used on non-computer controlled, conventional carbureted engines, used mechanical timing controls (vacuum and centrifugal advance).

As the name implies, there were four-electrical terminals in the four-pin control module. Two-large terminals, one for battery voltage input and the other was the ignition coil grounding terminal. The two smaller terminals were for the pickup coil leads. These modules are the most common and are still favored by many oval track racers and street rodders on non-computer controlled engines.



The five-pin control module was introduced in 1978 and the original version included a provision for connecting a knock sensor. This evolution was an attempt at electronic timing control. There are three different versions of the five-terminal control module. The three different types are not interchangeable.

  • HEI/EMR Electonic Module Retard used a wire connected to a switch or to an electronic control package. Under certain conditions, the switch or control package will ground the wire, which triggers the retard feature built into the distributor module.
  • HEI/ESC Electronic Spark Control used a knock sensor and an electronic controller. The knock sensor sends a voltage signal to the controller, which sends a voltage signal to the distributor module, activating the retard feature within the module.
  • HEI/ESS Electronic Spark Selection used an outboard electronic decoder which receives voltage signals from three sources: a manifold pressure switch, the distributor pickup coil, and an engine temperature switch. The decoder processes the information and provides a voltage signal to the distributor module to adjust the amount of advance/retard.
All the five-terminal control modules are used with distributors having conventional centrifugal and vacuum advance mechanisms.



Next was the seven-pin control module which was used on computer controlled engines. Because the computer controlled the ignition timing, there were no mechanical timing control mechanisms on the distributor. These distributors cannot be used on non-computerized engines. The seven-pin control modules are referred to as HEI/EST (Electronic Spark Timing) distributors. All timing advance was pre-programmed into the computer, using information from an array of engine sensors. Base timing could be adjusted, however.

Chevy distributors have casting numbers and casting dates, which can be useful if you are trying to find out the original application the distributor was used in. The housings are date coded and stamped with casting numbers of their respective engine or vehicle application. The numbers were either stamped into an aluminum ring that was wrapped around the upper part of the distributor shaft housing, had a stamped plate riveted to the housing or was stamped into the housing itself.


How the four-pin module works.
