Hot Rod or Car Craft did an article on which was the best big block to build. They included the BBC Olds Pontiac Buick Chrysler and ford. The way they determined the winner was by the Horsepower to dollar ratio. All the Big blocks came out pretty close with the winner being the Pontiac. I think it shows that all depends on your personal taste, but like many others I am a Chevy first and GM second kinda guy!!!
