Quote: I like taking the stock forged steel cranks and have them offset ground to 3.91 or 3.90, (whatever stroke you can get out of them) with BB Chevy rod size and B motor main size, works good in both 400 and 383 The 400 blocks have thicker main webs than the 440 and 383 do
You can get 3.91 out of a std b/rb rod journal , but doing all that grinding will get you close to the cost of a CCJ crank POSSIBLY a 4340 non twist forging ... but then adding in the cost of having it ground .010/.010 to fix it may blow that deal ...
