I knew you would like that lol. He does have a flowbench and a dyno so there must be a reason he is using the 50 degree stuff now. It could be in limited applications but I don't know his reasoning, I hope to test this and many other things on the dyno. The first test coming up is trickflow vs speedmaster/edelbrocks ootb and hopefully a set of bloomer heads. I would love to have a set of your ported speed masters to throw in and the finale would be the w5 top end I have. This would all be in the name of knowledge not a competition.
