i know ....now .thanks to jim ......its a roller block .but  had a flat tappet setup ..............they used the same block 87-95  for cars and trucks .but cars got roller setups and trucks flat setup ....roller blocks will also have 2 threaded hole on the side of the block where timing chain (cam gear) goes for a cam plate

so when i take my block to machine shop friday ,,,,if i tell the machinist that this gonna be a 383 ......will he know where he needs to grind for crank clearance (aftermarket crank )

I would give him all the parts so he can make sure everything clears. Dont want to take it back to him a 2nd time.

Most of the time unless he is gonna be assembling it, You will not know where to grind, You have to assemble it , find where the rods are gonna interfere with the oil pan  disassemble and then grind , assemble , ect ect until you get the whole the done, then take it all apart again and then wash the block again thoroughly and clean all your parts and then assemble it for the last time, The labor to assemble it will kill you if he does it.


I found this on google in .00005 seconds.
