Small Block Short Blocks

Stock 360 bocks are jet washed and then magnafluxed to ensure we are starting with a good core block. We then sonic check all core blocks to make sure all blocks have adequate cylinder wall thickness. Blocks with excessive core shift or thin cylinder walls are scraped. Good cores then have all casting flash removed and we enlarge oil galleys that feed the main bearings. ARP main studs are installed and the main bores are align honed. We then bore and hone the cylinders with deck plates to the first acceptable bore size (usually +.030). Blocks are then measured and the deck surfaces are parallel decked. The cam bearing bores are measured and honed to proper size for perfect cam fitment every time. Blocks are then final washed and cam bearings and brass freeze plugs are installed.

Rod and piston wrist pin sizing is checked and the rods are hung on the pistons. Ring end gaps are measured and filed for proper end gaps. Rod and main bearing sizing is checked on the balanced rotating assembly and the short block is then assembled by and recorded on a build sheet and all short blocks are supplied with a copy of this build sheet.
