{"product_id":"whipple-gm-big-block-moac-intercooler","title":"Whipple GM Big Block MOAC Intercooler","description":"\u003cp\u003e\nThe Whipple GM Big Block MOAC Intercooler combines Whipple's modular 671-based GM Big Block intake manifold with the MOAC (Mother Of All Intercoolers) intercooler system. The MOAC configuration provides increased intercooler capacity for Whipple twin-screw, Quad Rotor, roots-style, and other compatible forced-induction combinations.\n\u003c\/p\u003e\n\u003cp\u003e\nThe manifold is compatible with Whipple 3.3L, 3.8L, 4.0L, 4.5L, 5.0L, 8.3L, and Quad Rotor superchargers. With the appropriate billet adapter plate, the 671-based manifold can also support 671 through 1471 roots-style superchargers from manufacturers such as B\u0026amp;M and Weiand.\n\u003c\/p\u003e\n\u003cp\u003e\nCast from high-strength A356-T6 aluminum, the manifold is available for both standard deck (9.8\") and tall deck (10.2\") GM Big Block configurations. The modular design allows the assembly to be configured around the required deck height, finish, supercharger adapter plate, MOAC intercooler material, and thermostat housing.\n\u003c\/p\u003e\n\u003cp\u003e\nThe standard MOAC configuration uses a cupronickel (CuNi) intercooler core. CuNi construction provides excellent corrosion resistance and heat-transfer capability, making it especially well suited to demanding environments including marine applications. An aluminum MOAC intercooler core is also available as a lower-cost configuration.\n\u003c\/p\u003e\n\u003cp\u003e\nMultiple billet adapter plate configurations are available to support common supercharger and blower layouts. Depending on the selected configuration, the system can support 671\/871 applications, 1\" offset 1071 applications, B\u0026amp;M 250\/420 applications, and Weiand 256 applications.\n\u003c\/p\u003e\n\u003cp\u003e\nApplicable billet adapter plates are machined from 6061-T6 aluminum and are designed to maintain effective airflow distribution through the supercharger and manifold assembly.\n\u003c\/p\u003e\n\u003cp\u003e\nThe 671-based manifold architecture can also be adapted for other forced-induction combinations, including turbocharged or centrifugal-supercharger systems, when used with the appropriate custom adapter.\n\u003c\/p\u003e\n\u003cp\u003e\nFor applicable fuel-injected Whipple supercharger combinations, verify distributor clearance and any required spacer or adapter components before ordering.\n\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eKEY FEATURES\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eWhipple MOAC intercooler and GM Big Block intake manifold assembly\u003c\/li\u003e\n  \u003cli\u003eMOAC (Mother Of All Intercoolers) intercooler configuration\u003c\/li\u003e\n  \u003cli\u003eCompatible with Whipple 3.3L, 3.8L, 4.0L, 4.5L, 5.0L, 8.3L, and Quad Rotor superchargers\u003c\/li\u003e\n  \u003cli\u003eSupports 671 through 1471 roots-style superchargers with applicable adapter plates\u003c\/li\u003e\n  \u003cli\u003eAvailable in standard deck (9.8\") and tall deck (10.2\") configurations\u003c\/li\u003e\n  \u003cli\u003eMOAC Cupronickel (CuNi) intercooler core standard\u003c\/li\u003e\n  \u003cli\u003eOptional aluminum MOAC intercooler core configuration\u003c\/li\u003e\n  \u003cli\u003eNatural, gloss black, and polished finish options\u003c\/li\u003e\n  \u003cli\u003eMultiple billet supercharger adapter plate configurations available\u003c\/li\u003e\n  \u003cli\u003eOptional thermostat housing configurations available for compatible plumbing layouts\u003c\/li\u003e\n  \u003cli\u003e671-based architecture can be adapted for additional compatible forced-induction applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\n\u003cstrong\u003eApplication Note:\u003c\/strong\u003e Verify engine deck height, supercharger type, adapter plate, MOAC intercooler material, thermostat housing, distributor clearance, available installation space, and complete installation requirements before ordering.\n\u003c\/p\u003e","brand":"Whipple Superchargers","offers":[{"title":"Default Title","offer_id":67849518154050,"sku":"WC-9000\/9080","price":5991.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/6002\/9506\/files\/F198650176.png?v=1792633502","url":"https:\/\/whipplesuperchargers.com\/products\/whipple-gm-big-block-moac-intercooler","provider":"whipplesuperchargers","version":"1.0","type":"link"}
