Is there anymore block work to make a 3.875 stroke crank fit in a 350 block? The mains are 2.45. Can you use the same piston as a 383?

You may have to grind a little more rod bolt clearance at the bottom of the cylinders than the 3.75 stroke, but not much. As far as pistons, you will have you buy a special piston from wiseco, ross, je, etc.. this is why it is not as poular as the 383. It is however a nice "torque monster" alternative to a 406. hope this helps

Just doing some quick math i think you might be able to use pistons made for 350 6.25" rod 3.48 stroke. Combine those with a 6.0" rod w/ your long stroke. You would have to play with deck heights etc to get it fine tuned. JE may make a piston for that combo but I'm not sure. Might be easier in the long run to get a custom piston.

Now getting all that to fit in the block is another thing.
