The block has been race prepped: bored and honed w/deck plate, align honed, parallel decks, new cam bearing and brass freeze plus installed. The engine was professionally assembled and it comes w/build sheet. The engine has also been run on the dyno to break in the cam and tuned for optimum power, dyno sheets provided. Engine is complete from intake to oil pan. Distributor, water/fuel pumps, and carburetor are available at an additional cost.
This engine made 474 HP and 543 torque. It has a cam design for power brakes and makes 12” of vacuum @ 900 RPM. This is a small cubic inch version of our Street Killer Krate.

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.
