In 2005, Ford Racing Performance Parts introduced a {{cvt|4997|cc|L CID|1|order=flip}} V8 [[crate engine]] for use in [[motor racing]] and home-made performance cars, officially called M-6007-T50EA, but more widely known as "Cammer". Since then, other higher performance variations of the Cammer have been introduced for [[KONI Sports Car Challenge]] and [[GT4 European Cup]]. All versions of the Cammer are DOHC 4-valve per cylinder designs with a bore and stroke of {{cvt|3.7x3.543|in|mm}}. The Cammer achieves its larger {{cvt|3.7|in|mm}} bore by resleeving the 4.6&nbsp;L aluminum block.<ref name="Media.ford.com">{{cite web |url=http://media.ford.com/article_display.cfm?article_id=16767 |title=Ford Racing's New 5.0-Liter "Cammer" V-8 Crate Engine Offers High Horsepower and Easy Installation |publisher=Media.ford.com |year=2003 |access-date=2013-03-11 |url-status=dead|archive-url=https://web.archive.org/web/20060810082549/http://media.ford.com/article_display.cfm?article_id=16767 |archive-date=2006-08-10}}</ref>

The T50 Cammer crate engine, the least expensive and most street oriented version, uses derivatives of the cylinder heads, variable runner-length magnesium intake manifold, and camshafts first used in the 2000 FR500 Mustang concept car. These parts are unique to the T50 Cammer crate engine and are not found in any other production Modular applications. The T50 has an 11.0:1 compression ratio and exceeds {{cvt|420|hp|kW|0}} with the proper exhaust manifolds.<ref name="Media.ford.com"/>

The Cammer that has seen success in Grand Am Cup powering the Mustang FR500C is officially called M-6007-R50 and features a unique dual plenum, fixed runner-length magnesium intake manifold, [[Ford GT]] aluminum cylinder heads, unique camshafts of undisclosed specifications, and an 11.0:1 compression ratio. The R50 Cammer produces over {{cvt|450|hp|kW|0}} without restrictor plates. Upon introduction the R50 Cammer-powered Mustang FR500C proved to be dominant in Grand-Am Cup, having achieved five victories and podium appearances in nearly every race in the GS class during the 2005 season, giving [[David Empringham]] the championship title with the Multimatic Motorsports team, and Ford the manufacturer's title.{{citation needed|date=October 2012}}
