can a 383 block take the 400 bore ?

some local "experts" says it is posible but... how true is that

You would definately want to Sonic test the Cylinder Wall thicknesses FIRST, but off the top of my Head I would say NOT reccomended.

yeap, thats what I though, Thanks Bob.

I got an "incident" with my 400 block on cilinders and had to end getting 0.020" KB215 ( arrived today ), so selling locally the standard ones I had initally to built my engine. A guy with a 0.060" 383 was wondering about that... there is another guy thinking to make the same on another 383 he is trying to get locally. ( two posible buyers then )

So, now I can sell BUT saying its at his own risk, if they proceed correctly with sonic test... and wash my hands.

if you feel between the water jacket holes & the cylinder wall you can get a curved caliper in there the get a rough idea of the available wall thickness , I would still sonic check it if it measures good
