Mach One.
I like my First Generation cars, there my favorite body style. Second would be the 69-70's. Well at least in my book.
I would love to build a 427 for a Factory Five Replica, but the block alone would cost as much the parts, heads, and block for the 390 I want to build if I do get the FF5 Cobra.
Just think, a 450-500 HP 390 in a car that wieghs 1200 lbs less than a late 80's 5.0. Can we say VVVVVRRRRRROOOOOOOOOOOMMMMMMMMMMM.
I do have a 289 sitting in my garage thats I built 3 years ago. According to Desk Top Dyno its pushing a little under 300 Flywheel HP. That would scoot too, but WOuldnt have that Beastly Neanderthal Charm that Big Blocks Have (In other words I just want a Big Block).
