Hey Chuck what's difference between those two,3lobed or straight louvers application? Years? Thanks,Brett

Brett I do not have an answer for you I do know the louvered one is for a 66 442 with 4spd and I believe the L69 Tri-Carb option I'm not sure if it came with the 4 bbl as the assembly drawings show it with the L69 option. I believe both of these were used only on 4spd cars 67 or older. But again I just purchased this car a few months ago the last time I owned a 442 was 30 years ago.

Thank you very much Chuck. It's a never ending quest for all the applications of bits and pieces that Olds used. It might be interesting to know the engineering reasons behind them. Best of luck with your project. Brett
