408 Stroker Build / Intake Question
I would NOT use the cast crank for boosted applications. For that, if it were my build, you would have a Callies Dragonslayer in it. The cheap cranks are fine for moderate mixed use builds. They are not indestructable. I think the Scat/MP cast units are a little better than theEagles. They've been around longer and proven reliable. I know several over 600hp with NO2 that live fine. The Eagles were mde to undercut that price tag. As power levels are expected to eclipse 500hp I would expect to get a better crank. In terms of inish quality... Everything has a spec. Cheaper cranks tend to use the whole range, and many performance builders want exact so they have them fixed. Others are fine using something that is within factory tolerances and for their use they will be fine. The better the machining in terms of the block and all other parts, the more any crank can take without expiring. This is one reason I am so anal about what gets done and how. I mic the journals and if I see an issue it will get fixed. The last two Eagles I used didnt need anything by my experience, but they were not perfect. The last Callies I used was dead on perfect, zero taper, and identical to the .0001 dimensionally. Cheap cranks simply are not that well done. That's why they are cheap.
