Small Block V8 vs. Turbocharged Slant Six

1.- I would consider a good running 5.9/5.2 magnum with under 140k low mileage, as these are everywhere with 250k-300k on them. 350 bucks seems to be the going price.
2.- If done right, it is very hard to compete with boost, especially on the street. I've mildly played with the 2.2 Chrysler turbo's. Honestly, I dropped over 1/2 second for 3.00 dollars, that's right, 3 bucks at a pet store. What I've seen people do with V6's is amazing. Well mannered 3600 lbs of steel in very quiet smooth running cars go mid 10's. But IF it is not done right, wow the destruction that can be done, and the cost.
