1967 BB 390 hp

Re: 1967 BB 390 hp

Tonight I will put the shielding back in place and should be good to go. Again thanks to all and have a great day.

Tech Tip: Leave the shielding off and your coil will, definitely, remain cooler. The only time my shielding is on my car is when it's being judged...the only time!! Fewer chances for coil shorts, as well. Unless you listen to AM radio a lot, that shielding is serving no purpose whatsoever, except for show.

Funny, actually all I have is AM band, my FM is inoperable Thanks for the tip though

I bought the NAPA IC12 coil two weeks ago and I couldn't get the car to start with it. I ended putting the 202 back in.

Tim, Maybe a bad one? I've used many with no problems. The IC12 is a direct replacement for 1955-1974 Corvette, and 100's of other makes/ models..

What year/engine?

Richard, that's quite a list. It's a 1967 L36 with standard ignition. I traced it to the ballast resistor finally.
I always appreciate your help.

Ahhh, Good. So now you can carry a spare if that 202 should ever fail.

Rich,

I must be being dense here. You say that the Echlin IC12 coil is a direct replacement for 1955-1974 Corvette. Just picking 1966 Corvette, for example, does that mean the IC12 is a perfectly functional replacement for these Delco coils used on various’66 Corvettes: 202, 207, 210, 231, 232, 261, and 262 coils? If so, why did GM use seven different coils if one is sufficient?

Gary,

Putting aside different coils for transistor versus points ignition systems....

....You're asking me why GM AC Delco Products designed so many coil variations for each model year?

That is one of the infamous mysteries of all time. I've always wondered that myself. Maybe it was to keep everyone there at Delco busy? (Sarcasm intended, but probably true)

For example, TI(K66 Transistor Ignition) original factory coils from 1964 onward had several specific coils installed. But you couldn't buy one of those factory designated coils at the dealer parts dept. The 207 came about and replaced every one of them and that was sold instead of the several factory part numbers.

Some bodies probably got laid off or transferred afterwards. And the guy that came up with the 207 probably got a bonus.

They must have designed the 207 to meet or exceed all of the factory TI coils specs of every year. Likely to save money by offering one part number instead of several. The bean counters likely played a big role in that effort.

So as far as the Napa IC12, the Echlin guys in Poland must've done the same thing. They probably reviewed all OEM coil specs and came up with a single design that met or exceeded all of them.

Oh, and by the way, the IC12 worked fine for over a year before I found a NOS Delco 207 for a '67 L71 TI car. So much better than those repro 263's that were "JUNK".

I found a few Echlin papers for other coils which seems to correspond with their "direct replacement" methodology. One example attached below.

Also a pretty cool video of their 100,000 sq ft facility where they're made. So nice to see its not 10,000 miles east of there.

Rich,

Thanks. Amazing. And impressive.

Re: 1967 BB 390 hp

Yes those Delco Coil in the Delco Box are junk Dave will find you a original one for sure , don't even keep the Paragon Coil as a spare its not even good for a spare , just get your money back put it towards David Coil . Danny

I can't tell you about C2 coils, but I can tell you about C3 coils and leave it up to you to decide if our information is usable in your situation.

Coils were supplied to ST Louis as an assembly that included the coil mounting bracket. The Factory supplied coils had the last three numbers of the ASSEMBLY part number stamped into them in relief. As the coil mounting bracket changed in PRODUCTION so did the assembly part number and thus the last three numbers also changed. And also as the coil internal construction changed so did the part number of the assembly change in production. The coils supplied in SERVICE were a single unit and had the last three numbers of the coil part number applied to them.

BTW: That video applies to "coil on plug" units. I aam not sure it applies to our type of coils.
