Improved Racing Oil Cooler Adapters

Improved Racing oil cooler adapters have a low-profile for more header clearance. The adapters are machined from a single piece of billet aluminum and black anodized. For additional clearance with reliable sealing, they come with aluminum gaskets fitted with Viton® seals, and the adapter mounting holes are counter-bored so the mounting bolts fit flush with the adapter surface. Select Improved Racing oil cooler adapters are also available with a built-in thermostat. Oil coolers help prevent the oil from getting too hot, but are also prone to lowering oil temperatures too much, especially in colder weather or during highway driving. The rebuildable thermostat speeds warm-up and helps reduce engine wear and horsepower losses by preventing oil temperatures from dropping below optimal levels. Features and benefits * 100 percent bolt-on solution; no fabrication, bending, or line modification is required * Viton® seals throughout for maximum reliability * Oil exiting the adapter is filtered oil * 6061 T-6 billet aluminum construction with black MIL-A-8625 Type II anodized finish * Standard female -8 AN O-ring boss threads for optional anodized adapter fittings in your choice of -8 AN, -10 AN, or -12AN lines * Depending on application, includes port(s) for oil sensors or turbo oil supply * Includes all necessary hardware * Limited lifetime warranty

World Products Motown Race Engine Blocks

World's Motown blocks are without a doubt the most feature-laden, engine builder friendly, cast iron blocks on the market. And because of their superior temperature control and rock-solid stability, experts claim they're worth up to 20 hp more than other blocks on the market! At first glance, one of the more noticeable differences between the World Motown and OEM Chevy blocks are the 'bulges' at each cylinder. That's because the Motowns have thicker cylinder walls, and the water jackets have been expanded to provide required cooling. Order the model and options preferred for your application. Important features are as follows: * Made from high-density cast iron * 9.025 in. deck height with .600 in. minimum thickness * Dry sump valley scavenge lines drilled * Clearanced for 4.000 in. stroker crankshafts (H-beam steel rods) * Integral mounts for spin-oil filter * Dry sump systems can feed from front or rear of block * Available with 4-bolt nodular or splayed billet caps * Can be bored to 4.200 inch maximum * Water jackets expanded for better cooling * Standard Chevy cam location and cam bearings * OEM starter, fuel pump, and engine mounts (dual) * Blind tapped head bolt holes for extra integrity * 100 percent compatible with OEM parts * Indexed lifter bores (can use standard-height lifters) * Main caps are located by dowels (not OEM outside register) * Weight: Approximately 190 lbs.
