E-street vs Promaxx vs 440 Source

For the goal, he won’t need higher “RPMing” heads.
He is making sense.
There are more folks than just me asking this very question. Joe showed his E-street inspected by Ed. Ed did a great job but I wasn't impressed with the E-streets OOTB. I think anyone who is considering 440source will also be looking at Promaxx, and probably E-streets, and even the Sidewinders that someone posted a link to. As many machine shop/head guys that we have here on this site, I thought it would be a good thread for "Insight". I'm very interested in others experiences. It's not "me specific" or my personal "build" as Jpar wants to talk about ET goals and gears, and Winnebago's :D. As for Jpar, he works overtime to try and get havoc started in my threads.
