odd fire huh? so you had a 77 and older 231?
78 and up is evenfire
then the fuel injected ones from 3800 series 1 to 4?
well they actually split the oddfires and even fires in 77, they were making odd fires for the first half of 77 and then the second half they switched over to the even fireing engines. im not sure about the newer engines i dont know much about those. do you or have you had a buick?
