Let's put a mild 8.2:1 360 on the dyno.

The formula is easy: Buy what you honestly need, not what you want. That's why in a lot of cases I ask "why *** horsepower", or "what cars have [they] driven". Most people think they need more than they do, becuase the basic combos they have are so misunderstood and poorly tuned. One of the best take-aways from IQs dyno postings should be that: Match what you want to what you need, educate yourself to how to make these antiques run properly, and the results are there.
