First thing we do on all blocks is to pressure check them before we do any machine work. We have had all of them to leak at one time or the other. We then line hone the blocks to size before the block goes in the RMC CNC machinig center where we check the decks and bors to blue prints. If all check we will set the sleeves ion the block and make sure they are above the deck about .002 to .004. On the Pond blocks we do have line hone the cam tunnel and the Shelby has this done. We have to size the lifter bores on both blocks and make sure that they are not to big. From time to time we may have the install a bushing in one if it is to big. We then do the boring in the CNC machine if needed by the factory bore spacing and angles. Block is them honed with torwue plates to the size needed and for the rings to be used. Block then has the bottom of the bores deburred to remove any sharp edges on the sleeves at the bottom that might cut into the piston skirt. We deburr some other areas on the blocks and do some oil passage work as well. There are certain galleys that we may drill out bigger depending on the use of the block. We drill and pin the cam bearings on the Pond blocks so that they do not move on us. We also do complete lifter bore bushing on some of tha all out race blocks as well as roller cam bearings. We drill the blocks as needed for SOHC applications for returns. Every now and then you will find a galley plug that needs to be tapped deeper as well. You will also find a head bolt hole that is not tapped all the way to the bottom every now and then. You just have to check everything and that is what makes this shit so fun some times. Good luck, Keith Craft
