Is it smart???
i think it's a great theory, as opposed to small/big block running costs all the time, you get to just tick around with the economy of a six until you want it.
Don't get me wrong, i love my smallblocks, but with technology available (not to mention the bargain basement price), i've even considered removing one of my sets of webers of a hemi6, selling them and funding a turbo build.
There was also the article i was reading about using a slightly smaller turbo than reccomended for a daily driver (kicks in earlier at more everyday revs).
just out of curiosity, what would the weight difference be between a turbo 6 and a smallblock be?
