Maybe you could explain your rationale?
Simple enough,is it not easier to turn down the 3.75" stroke/pontiac rod journal crank to the BBC rod journal size if that's what you wanted?

Kinda hard to add material to the journal after the fact,is it not?

Rather than requiring those who desire a direct replacement sized crank for their existing combos change the rods and/or pistons to make the bbc journal crank work?

You say use the eagle 6.635" rod,that's fine,but either way you'll need to change something,either you'll need to open up the pontiac piston pin bores to use the .990" pins,or re-bush the brand new rods to use the pontiac .980" pins.

Lets see,cost of rods,machine work to pistons or rods,the crank itself,now I'm into the swap for well over a grand!

Maybe chump change to some of you,not for me!

I already have the pistons,I dont wanna mess with the rods,why turn your back on the basic stuff when it would be easier to make these 3.75" cranks the OE dimension first,and lets those looking to improve the package with the bbc journals change the crank themselves,after all is it not likely they'd be "cleaning up" these cranks dimensionally anyways,what is the big deal with those wanting the chevy journal having to turn down the rods to get that???

For somebody looking to just upgrade what they currently have to use the forging your telling them "tough luck cheapskate" and in my opinion that's just plain arrogant and extremely shortsighted.

I have 1 complete and 2 more "in-progress" 400 combos going together for the race car,and these use the off the shelf pieces,I have no desire to re-invent the wheel,just use these parts with as little grief as possible,cheap you say,damn skippy I reply,I have to be if I expect to get this car to track this decade,ask me that choice was extremely short sighted,and just plain boneheaded,no matter who is "spinning" that fact,and how much they argue their point.

I have zero need for the chevy journal 3.75" crank,but I would have been interested in at least two pontiac journal forged 3.75" cranks to begin with,and another one after the other motor(s) are together and I pull apart the first motor to update and refresh it,so already Ohio crank has lost four potential crank sales for those 3.75" stroke forged cranks by using that flawed logic.

I guarantee the forged 3.75" cranks sales will suffer for that logic and choice.
