I was not going to go through the expense of the caps unless I could find a std bore.
Anyway its a cast Eagle crank. The crank is all good for a cast. Whittmores last engine. He ground it .010-.010 and polished the trust. As is it was way off. .001 tapper on the rods and bent .004, new. But its all balanced with billet steel rods and Ross 4.155 FTs.
I would like to put a steel crank in but thats 1200$ by the time you are done with re balancing and maybe grinding.
Any of you guys see a problem in pushing 650 HP through it. 350 High Ports and Crower SR. >667 .270-.275 108.
I dont plan on running it past 6500 RPM.

The last time I used an Eagle cast crank, it was in an engine making around 600-650 HP. That engine ran great right up to the point where the crank broke in 3 pieces at the 3'rd rod journal back and split the block in two. All the bearings on that crank looked good, so it was just a matter of the Chinese cast iron couldn't hold the power. That was the last time I used one of those cranks. I just don't trust them anymore. I'm quit certain a factory crank would have held up just fine in that engine. This was back in the early 2000's when these cast Eagles were the only option before all the forged cranks came out. Maybe they have gotten better, I don't know. Never been willing to try another.
