I know what you mean but, the way I want to build the 427, it will rock. If I go the small block 427 then it will fly. For I am looking at evey way to build a 427 right now. I want it to be a wiched motor, but still street legal. I am out to have fun with it. That is all. But the 4.6L's are nice, but it is the new 289. Witch they are a nice motor too. You can do alot with them too.
