Three new and further developed Group 7 works cars were built for the 1969 Can-Am series, using at least one of the original M8A monocoque.

They differed from the earlier cars in body design, using wings that stood high above the tail on suspension-mounted struts and had new 7-litre engines built by George Bolthoff, an ex-Traco engineer. There were minor detail differences between the M8Bs and the M8As. The 1969 cars used larger wheels - 15 x 11 front and 15 x 16 rear. They were unbeaten in the 1969 season and took Bruce to his second championship.

The most noticeable difference was that the rear wing was now mounted high on pylons, like the Chaparral 2E. The wing mounting pylons passed through the bodywork to attach directly to the suspension uprights. This arrangement allowed McLaren to run softer springs than would have been required had the massive rear wing been attached to the bodywork. The body was also widened in order to fit one inch wider wheels, now 15 x 11 front and 15 x 16 rear. The 1969 engine was a shorter stroke, larger bore version of the 1968 engine. It was built by George Bolthoff and developed 630bhp from 7,046 cc (430.0 cu in). Two complete M8B race cars and one spare tub were built using parts from the three M8A's.
