Show original supplier description
The G Force GF-CM is a motor mount adapter engineered for 1984-1995 Ford Mustangs, specifically to facilitate the installation of a Small Block Chevy (SBC) V8 engine. This bolt-in adapter allows for the easy integration of a Chevy V8 into your Mustang. However, larger oil pans may require minor K-member gusset adjustments. It's important to note that carbureted engines sit taller and may necessitate a modified hood, with a 2-inch cowl hood typically providing adequate clearance. When installing these headers, the stock clamshells will not work, and aftermarket mounts are required. Some Fox Body Mustang applications may also require an aftermarket steering shaft with a small universal joint, as the large rag-joint steering coupler will not clear. All sales of SBC Mustang Headers are final, and customers are advised to contact the support team with any questions prior to purchase.
