Well the picture of the heads side by side came from the LX forums actually. As did the flow numbers.
Either way, if you have some good links and information please let me know. I'm just trying to learn and by no means have I fully figured out this engine
My best advice it to search everything you can find on the LX Forum...triple crosscheck everything before drawing even minor conclusions.
I have been living modern Hemi engines and drivetrains for the past 10+ years and own 2 of them. It takes a long time to become knowledgeable.
And no, there aren’t any quick summaries out there you can read and become expert...you have to earn the knowledge by the sheer persistence of obtaining it.
