Lots of used forged takeout 6.1 cranks out there for cheap ($150). Not worth running the stock 5.7 crank if building the motor IMO
Been looking, I haven't found one that cheap, let me know if you know of one somewhere. Best I found was $450
Try LXforums. Or I have one out of a spun rod bearing motor, just no box for it ATM.
Isn't there the higher rpm oiling issue though with the stock cranks?
They are cross drilled. The drag pak guys turn em to 8200-8500 without issue with a 9 qt pan + 3 qt accusump. You will run a 6 qt swap pan dry around 7500 (ask Joe- he knows first-hand).
I had a 10qt pan with belt drive Barnes oil system turning about 7200-7300 RPM and the stock crank......#3 rod quit oiling...DEVASTATING results. Molnar crank and no problems at 7800-8000 RPM. This has been hashed out for quite awhile. I, and many others, have concluded that there is a problem with the stock crank oiling. JMO...$.02...etc. Try one yourself and report back later.??
