I have a few 383's out there in AMC cars but now I finally get to build one for a Full Size Jeep!
To get to 383 cubic inches, it requires a 4.155" bore and 3.53" stroke
Here is the block all cleaned and ready to go.

I love part numbers with "RD" or "X" in them. "RD" means Research and Development but a "X" could mean anything.

This block is a late Jeep block. The extra core plugs in the back were added to the drawing 2-5-1979

I Sonic check the block before and after boring. I check several places until I find the thinnist spots.

This is nice thick block. The absolute thinnist spot is .110". This block could have been bored out to the 401 bore of 4.165" and would have still been ok. I go to 4.155" because it is a standard size and to stay on the safe side.

Here is the purdy crankshaft. I had it off-set ground to a 2" journal with a 3.53" stroke.

On the performance engines I drill out the main bearing feed holes to match the 5/16" oil feed hole below it.
