Correct coil for '70 LT1?

[Mr70]

Those really stood for the last 3 digits of the part.i.e. Coil #1115293.
I've seen em embossed 12V,some 12-V,some BR and some B-R.
Why I don't know,but all have been found to have been used on the line as original equipment.

Just in passing. LT/1's in deuces, although they're stamped as a Z28 motor, use a 293.

[YENKO DEUCE REGISTRY]

Schoneye is correct, the LT1's in Deuces were all 293's.

Any thots Marlin on why 293s for the LT1s in Deuces and 270s for LT1s in Zs and vettes?

Sam, those numbers are for the use of the assembly line workers to put the correct coil bracket on the correct car for hood clearance and air cleaner clearance etc I believe. I think there were maybe 3 different types of bracket angles. The 69 Z/28's took a 298 coil. Same as the 293 but that number determined the bracket offset. The guys at the CRG Site or maybe Jerry MacNeish or Brian Henderson can explain it better.

So Sam, you're saying that maybe the Deuces had different (more) hood clearance than the vettes and Zs and the 293 or 270 would dictate the bracket angle thereby providing appropriate clearance?

[Salvatore]

Believe me Sam, I am NO expert but I think that would be correct. The coils 293 and 298 I believe have the same ratings. I am not sure if the 270 coil is a hair shorter than the others or not. My 69 SS nova has the 293 coil on it. My Z has the 298 coil with the flat hood.
