Scufty- sorry about hijacking your thread. My 390 fe has been bored over to a 410 cid. Would upgrading the heads make a huge difference or just a suttle change for a big buck and a lot of work? Are we adding let's say 50 hp or a 100 hp or just opening a whole can of worms where one thing leads to another. I can live with it the way it is now, but it's never enough when you can have more is it? Thanks
