Best 273 and 318 builds (NO 360's please)

After batteling it out in several forums, I realized that it's pretty hard for the little small block guys to get any big power tips for they're mills without being lectured about the advantages of bigger starting points so I decided I'd start this thread for all of them. Let's get this out of the way, There are plenty of reasons why starting with a 360 can make for a cheaper, easier, or more streetable build, but this thread isn't for all of that. This thread is to benifit all the guys who want for WHATEVER the reason to start with a 273 or 318 and make big numbers on the dyno streetable or not. I know that there are lots of ways to do this, 390 strokers, magnum and swirl port heads, superchargers and turbo's, even the probably bad idea 360 crank middle weight stroker.
The only rule for this thread is no "ditch it for a bigger motor" posts!
Sooooo... Let's see what you got guys!!! :cheers:
