I have an opportunity to buy a Boss 302 crankshaft for $100 (maybe a little less). This is a forged steel crankshaft good for as many horsepower and RPM as I would dare put into it. I am told it is in new, unused condition. Here's the catch - the rod journals have been turned to Chevy size (2.100 inches). As I understand it, these journals are slighhtly under-sized (stock 302 rod journals are 2.123"), but that rods are available (e.g. Crower Sportsman for $570).
I guess this effectively increases (slightly) the rod length (which improves rod ratio which is a good thing) and also results in slightly improved friction characteristics due to the smaller journal diameter and bearing area.
Aside from the oddball rods needed, are there any other problems with this crank? Any reason I should stay away for $100?
