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.
