    Default Chips are flying..................... Crank grinding

    As delivered from Paul Kane:

    120 lbs of AMS 6415 chromoly steel




    After a day of machine work at Crower:



    It's going to loose in the neighborhood of 40-45 lbs. It will end up being 4.5" stroke with 2.200 rod journals

    I'll get a couple more pics during the process.

    A project for next year...... just decided to get this part out of the way now.

    Well go-DDAMN that is one sexy bitch!

    Something that I fogot to mention (in case you missed it on the other forum): Notice that the snout of the 3.875" stroke commercial steel truck crankshaft (on its side, above) is not shiny-machined but is the same discoloration as the rest of the crankshaft (even though all the journals are nicely polished). Be sure to ask Danny to take a closer look at it and determine whether he thinks that crank was simply bead-blasted or if he believes it has been ion plasma gas heat treated. That is a very well prepared forging and it wouldn't surprise me at all if the workmanship included a heat treat as one of the final steps.

    Enjoy,

    LO

    FYI to all: AMS 6415 chromoly is a 4340 chromoly recipe which meets a very stringent Aviation Material Specification. It is probably the strongest chromoly crankshaft material known to have ever been commercially available for Ford crankshafts. In fact, Bryant Crankshafts purchased the entire remaining stock of raw forgings from Ford's SVO department when they were put on the chopping block and so the above pictured forging is precisely what Bryant starts with when they carve you one of their famed Ford crankshaft forgings.

    You're going to have one hell of a crankshaft there, Jon.

    If you switch your recipe to BBC instead of BBF, you could probably change that to 600", 1040+hp, 11:1.......

    Would that be Chevrolet horsepower or real horsepower? Like Ebay or Craigslist boats...They all go a 100+ MPH.

    Hey now ...let's not get personal.......

    That was my attempt to under sell and over-deliver. It will probably make 940 at about 6,200 ........

    512" ........ on the TT deal.

    This project is on a longer time-line. I just wanted to get the crank done and out of the way.
