So I might as well give you mine. In the end it will come down to personal preference. But there may be some things you should consider. If you are concerned about the history of the original Cobra, it is simply a fact that the small block (289) wrote the racing history and that the so called cobramen (Gurney, Hill, Bondurant...even old Shel) much prefered the small block and refered to the 427 as the "Turd". However, that was then and this is now and there no doubt that today... 427 is the magic number and you will see the disappointment on faces of people who will always ask you " Is it a 427 ?". Now, I have a small block 351W and I am very happy with my choice but if you ever intend to sell your car, the life cycle cost of the 427 is much cheaper than a small block largely because of re sale. Whatever you do will be right if it is what you want to do...this car is all about expectations...
