[QUOTE="GTSpartan, post: 1569925, member: 21531"] What does a '03-'04 cobra engine weigh? I think I heard (can't validate) somewhere around 600+ lbs. If thats true that is pretty heavy for an engine of that size. For straitline acceleration an iron block is probably best, but overall vehicle dynamics suffer greatly, especially the cobras with the strut suspension and high center of gravity. If you only care about going strait, I would definately go with iron, but I am talking about total vehicle performance. I don't know much about Ford blocks nor do I pretend to, but I have seen very high HP cars with aluminum blocks handle the power reliabely. And for some who think they will just add more power to a iron block to offset the weight, that will further decrease dynamics because you now have to deal with more abrupt weight transfer. Not trying to start anything, just giving my opinion becasue this is a very good topic of discussion. [/QUOTE]
