to get 383ci. Take a 350 bore it 30 over
and drop in a 400 crank.
Or take a 400 and drop in a 350 crank.
Not sure why you would want to go the second way.

a 350 crank in a 400 is a 377 not a 383

With the help youre getting on this, the safe way would be to write a check to a engine builder!

I left the boring of the 400 30 over because like I said why would someone do it that way.

when your stroking a engine the bore is not what makes the cid it's the bore and stroke of the crank you can either run a 350 block with 400 crank gives you 383 cid or you could run a 377 cid wich is a 400 block and 350 crank bolth are good combo's just depends on what your using it for as to wich one to use

377 is the high rev motor. (Big bore/short stroke)
383 is the low rev torque motor. (small bore/long stroke)

Either are good just depends on what you want to do with them.

Sorry guys had a short.
