I am restoring a 1969 COPO. One of the missing components is the coil. I've look through the assembly manual and the parts manual and have researched other books only to be disappointed because I didn't find the answer. Does anyone know which coil is correct, the 270 or the 293?
Thanks!

What engine and model 69 COPO are we talking about ?
What distributor do you have, point or TI ( alu. or cast iron ) ?

Hi Bob,
Thanks for the reply.
The car is a 9561 MN COPO, which is the 427 CI engine with the M-22 4-speed trtansmission.
The distributor is aluminum with points.

Jim,
The distributor you should use is 1111499 with 1115355 vac. advance can and the coil should be 1115238 stamped 238 BR.
Make sure you use the correct dist. or timing curve will be incorrect!
Hope this helps?

Thanks Bob.
Where did you find this information? It may be helpful for me later to get additional help.
Thanks again,

Jim,
The coil and bracket are an engine assembly, so the 69 AIM would be of little help.
In this case I used the Chevy By The Numbers and the GM 69 P&A (rev 10-1-69). The CBTN on page 242 shows the 1111499 dist. used on the 69 396 & 427. To verify this I used the 69 P&A 2.361 page 2-24.
The 69 P&A group 2.170 page 2- 4 shows 3 coils 1115202 (1.8 OHM resistance too high), 1115207 (TI coil), 1115238 (1.3 OHM correct resistance).The 293 number you mentioned is used by Rick"s but I think that is an GM assembly number for the coil and bracket. Look at 298 w/cowl induction and 270 wo/cowl induction in Rick's cat.,now go to the 69 P&A group 2.183 page 2-6. 1966876 w/cowl hood and 1971011 wo/cowl hood. The brackets are different not the coils.
Sorry it took so long to respond be am working on a 67 Camaro and 67 Corvette and they take up a lot of my time.

Bob,
Thanks for the info. I have the ASM and the 67-70 Master Parts Cat. I guess I'll get copies of the others.
Hope things go well with the 67's. Are they both numbers cars? Rare?

Try to use P&A's(69)that are as close to the year AIM's (69) as possible. This cuts down on GM part # substitution. Try to get verification from at least 2 references.
Both cars are (will be) drivers and will be shown. I have taken some latitude with some of the RPO"s ( 7 blade fans etc.), gets hot here in FL.

Old thread revive. So a friend recently found and bought a copo. It spent its early life as a drag car (no surprise). It has absolutely not one component of its drivetrain that is original to the car. My friend is trying to get this car back to semi correct drive train. So he comes down the other day with a shopping list of parts. He asked me what was the correct coil? I tell him that I believe the 293 coil is correct. To make sure I look it up. But I am unable to find a definitive answer. I can’t remember where I got the idea a 293 was correct? In fact, I don’t see any threads, other than this, that discuss this topic. And this thread leaves the reader wondering and not answering to at least my satisfaction. So, what is the correct coil for a L72 copo please?

Bentley by coincidence I was searching over at sYc just now for Sun tune-up sheets for a 302, and happened to find a 2015 post where Jason (SuperNovaSS) had posted pictures of one for a 1969 427/425hp - which lists the ignition coil. However it appears to be 1115290? Can't recall ever seeing one before, wonder if it may be a typo? No idea if these sheets are 100% accurate......

Most BBs in the CRG db have a 293 B-R coil.

I have most of the Sun tune up sheets from 1968.
-
Tim, I have the 1969 302 Sun Tune Up sheet if you need a copy.

Rick - thank you, I'll PM you to avoid muddling up this thread.

I got the same information, which is pretty simple.
1967-1974 1115238. Stamped 238 BR for V-8
1967-1974 1115202 Stamped 202 -12V for all but V-8
This info comes from Chiltons Labor Guide and Parts Manual 1974 45th year
This book tells the amount of time required to repair a car as well as all the part numbers so the mechanic can walk over to the parts counter and get the right part. Great Resourse.
-
But that's not correct.
69's had the 293 coil.
-
Your right but I wasn’t wrong, we both gave partial listings for there was also a 298 for the 69 and a Transistorized Model 210. My original numbers were the Chevy Parts Counter version. But as shortages arise other units were used from other lines.

Shortages? What shortages?

238 and 202 were never used on Camaros from the factory. That is wrong information.
Original coils and starters are very poorly documented in parts manuals. I have 3 or 4 GM parts manuals (from 68/69, not later years like 74) and none of the listings are complete / correct.
-
Though not a COPO, both my 67's L35's still have their 267-BR coils.

I started a research topic.... :)
Which forced me to find many of the answers.
