E-street vs Promaxx vs 440 Source

You nailed that one!!

As for this thread........ for a 440 making slightly over 1hp/ci....... any of the proposed options will easily get the job done.
Pick one and move on.......

Thanks to all that contributed. IF I was to order today, I would order the Promaxx. Guy was super nice on the phone, and all testimonies on and off the site have been pretty positive with Promaxx's valve jobs and such. Thanks again :)
