Cylinder Head Porting and Power Production

did it run at the track?

Of course not, this was his latest video--Napierville is closed right now. Engine wasn't exactly a mild rebuild with some very nice AFR heads and I think best pull was near 580HP/580tq. Even more curious now that I think about it is the requirement for a bigger carb when using a dual plane manifold--which this BBC was. I know what I've seen and it lines up as far as what the dyno shows us. J.Rob
