GT's have Super Charged 5.4 litre V8's. Same design as Grandpa's truck engine.
Pantera's have 351 Cleveland V8's. Clevelands were produced 1970-1974 only. These were considered big blocks and were produced at the Cleveland engine plant and dubbed the 335 series engines. They are rare. They were engineered in the late 1960's for the horsepower war, which died a quick death in the early '70's with the energy crunch of that time. Ford engineers designed this engine to breathe with huge intake and exhaust ports. They were also durable and could rev at 6000 all day. They are popular with the drag boating scene as well. They share design with the 429/460 known as the 385 series engines.
Ford also produced a 351 Windsor, a small block derived from the 289/302 V8's. Built in Windsor Canada.
Other than physical size, the Cleveland has a dry intake manifold where the Windsor is wet.
Though both displace 351 cubic inches, they are of completely different designs but some parts can be interchanged.
Cleveland and Windsor bell housing partterns are the same.
Just some history for you. These were my teen years. No jap scrap n those days.
