On the 360 stroked to a 408 what mods need to be done to the block?

Check clearance of rods at pan rail, min. should be .060". Check clearance at camshaft (depends how much lift it has) should also be a min. of .060" cam to rod. I've read in some mopar magazine over last few months. *360 blocks made from 1971 to 1974 with casting number 3418496 used same cores as the 340 CID engine, meaning overbores 4.040 ,4.070 ,4.100" do the math caution on the 4.100" to make sure the core has NOT shifted .I have done one 360 to 4.100"
but not with a stoker crank. *422 cubes* might be wild . The later blocks are thin wall castings and larger overbores are usally kept to .0030"
