440 Crank in a 383

The 383 block is a much stronger block than a thin cylinder walled 400 block. There is absolutely nothing wrong with a stroked 383.

Not everyone needs huge valved heads and 383 blocks are still available. Great sleeper combination. However as other have said skip the machine work on a OEM 440 crank unless you

know someone that will do it for free. By the time you pay to turn the counterweights down and then have the mains turned down you can buy a 4340 stroker crank for not much more.
