I have a couple tunnel rams and wondering if ones better than the other. Its a mild BBC 468 that was in my Southwind but its going in a 19' CP for next season. I ran the Edelbrock last season with a couple Holley 1850 600's and plan to run the same carbs. The other one is a Weiand I believe Hi Ram? The Edelbrock has the good port bad port deal and seemed to run pretty good. Just not sure if it makes a difference or not? Heres a couple pics.
