Have finally made the payment for the '56 Bel Air, and taken possession of its papers. The vehicle should be joining us within a week, Insha Allah 
I really don't know who's more excited at the prospect...Shayaan, or I! Of course, this opens up a whole new Pandora's box of possibilities. It actually makes me wonder whether an LS1-powered, fire-breathing Six Foe would be a better option, or an LS1-powered, fire-breathing Bel Air. To the best of my knowledge, this would probably be the only high-performance Bel Air...since most others have been lovingly restored to stock or near-stock by their respective owners. Then again, I really don't know of any high-performance Impalas, either. 
All of this is a delicious conundrum...that is really quite appealing. The Six Foe is a sleek, long, low beast...which has a beautiful, predatory stance. On the other hand, if the Impala is a raptor, the Bel Air is more of a bull...and within its macho, butch lines, lies its intrinsic appeal. BOTH vehicles are going to be resto-modded, regardless...since they're already lacking matching-numbers engines and transmissions. And with the high-performance power pack on its way...BOTH cars have the potential to be very, VERY fast indeed.
So, gents...with regards to fitting the LS1 motor...
Six Foe or Bel Air?
Candid advice would be much appreciated.
Thanks!
