Hi, how much interference is cosher on a cast sleeve? My friend did it for me where he works, mostly on big truck and deisel stuff, it's a 429 and he said he pressed in with .003 interference, now I found a book that said stick to .001 interference as not to stress the block or adjacent cylinders, all the cylinders will get bored to .040 so stress to the block will be the only downfall, maybe I just worry to much it will probably be fine what do you think?
