How do u guys feel about putting a 440 crank in a 383 wat does this do to the engine, increase stroke or anything of that nature?? Has anyone. Done this before?? thanks
Don't gorget that you may have to clearance the crank to the block, and turn the 440 mains down to 383 size I believe. I may be mistaken!!
How much something like that usually cost in a typical machine shop?? And what exactly do you mean by clearanced?? like what needs to be. Clearanced? i wanna know what I'm talking about when I explain to someone what I need done to the engine thanks
As was said, counterweights need to be reduced in diameter and main journals turned down to B wedge size. As far as the amount removed... there is no surface hardening on factory RB cranks unless it's a 426 Hemi. However, it is a lot to be done to a factory crank. It is not cost efficient IMO. Best bet is the 440Source B wedge 3.75 stroke crank. Better part, stronger, heavier (which means easier to balance with the RB rods), and drop in.
