Have a 69 Commando Wagon, 231 & 400 automatic. But unsure if I have a Odd or Even engine. The casting # 1254083 GM 4 shows to be 75-87 from my web searching. The sites I looked at say it is an Even fire engine. But it does have an Odd fire distributor. It runs, but is it right ?
Would /Could an Even Fire run with an Odd Fire HEI ?
Did Buick use the same block to build Odd and Even fire engines when they transitioned from one to the other ?
Also: Is the HEI coil on the GM V6's all the same, or is the Buick reversed polarity ? saw this mentioned, but parts guys look at me funny and say they do not find a Buick specific coil.
