Which Delco Coil do i need?
 

Looking to use an old stock replacement Delco coil for my Lemans. 389 AFB with points. Do i need the Delco 511 or 512 or either? i Can't seem to find out what the actual difference is.

Good question. I have had both. Back in the day, as long as it was not T.I., we grabbed whatever came out of the box. It always worked.

ACDelco recommends U505 for 1955-74 Pontiac´s.

Looking old stock here. Don't want to use currently made crap coil. I have found sources that state both D 511 and D 512. Can't find what the difference actually is.

The correct original coil for a 65 is 1115214. Is that what you were asking??

"Bill"!

Bolt on either one and run it. It will be just fine.

I'm thinking geeteeohguy is right. I'm asking which REPLACEMENT Delco Remy Coil is correct for my application. My 2 choices are the D 511 which is part number 1115202 or D 512 which is part number 1115238. I was just wanting to know which one was intended to replace the 1115214 that Bill referred to. I have found listings referring to both, but don't know what the difference is. In fact i don't understand why Delco has soooo many different blasted part numbers for a 12v external ballast coil!

*speculation warning*
probably minute differences in manufacture, and as stock was depleted of one type, then another one became it's replacement.

The 1964-67 replacement coil was #1115134. (1965 original #1115241, 1966 original #1115037).
1968-74 replacement coil #1115238 was used (1970 original #1115410).
Later D512 replaces both.
Primary resistance 1.7 - 2.0 ohms @ 75°F
Ignition resistor wire 1.32 ohms @ 80°F.

D511 is replacement for 6-cyl engines (1965 original #1115184, 1970 original #1115414).
Primary resistance 1.4 - 1.7 ohms @ 75°F.
Ignition resistor wire 1.80 ohms @ 80°F.

Hope this helps some.

Thank you Kenth! That is exactly what i was looking for. Last night i did find the specs on the coils, but couldn't find the application for certain. I'll be picking up a 512 in the near future.

1115187 was the production line coil in 64, 1115214 in 1965

that's some great info!!

1965 - 214
1966 - 037

Note mistake, Engine code WS and YS should be switched.

Chris.

I stand corrected, should be 214 for 1965, not 241 as i wrote. Thanks Chris!
