Pontiac V-8's are often referred to as "middle blocks" 383 Chrysler engines are also referred to in that way. 287-455 cubic inches covers allot of ground. Eagle stating some HP numbers for their crankshafts is literally just a guess, unless they have done some destructive testing, which I doubt. Small block 500 HP? Big Block 700 HP? Middle block Pontiac 600 HP?. How does that sound? It's all just a guess and speculation. If buying an Eagle crankshaft, very important to have it carefully measured and checked for surface finish. Especially the thrust surface on #4 and the areas around the gigantic oil feed holes in the journals. There are certainly much better crankshafts to work with in the aftermarket than Eagle. IMO, stock Pontiac Arma Steel or cast "N" crankshafts are superior to anything Eagle sells in the cast crankshaft line. Forgings are much better for performance builds of course.

Yeah. I don`t get off to any absolute hp or rpm numbers. 700hp? 5500rpm`s?
