With an aluminum engine block, the V8 used a split port design with two intake ports per cylinder, as well as variable runner length intake manifolds.Īll examples of the engine made in 1999 or earlier had blocks cast in Italy, by Teksid S.p.A, a subsidiary of Fiat. The first four-valve development of the Modular family, the new engine employed dual overhead cams (DOHC). Part of Ford’s Modular engine family, the new mill shared its 4.6-liter displacement with the company’s standard V8, but was much more technologically advanced. Let’s take a quick dive into the world of the Four-Cam V8 that you’d know as InTech. For the first time ever, a Mark would debut with an engine not offered in other Ford or Lincoln products. One of the most important differences between the Thunderbird, Cougar, and Mark VIII was the latter’s exclusive V8 engine. The Cougar was roughly the same depending upon trim level. Worth a quick comparison, the equivalent Thunderbird weighed 3,536 pounds with a V6 engine or 3,725 with the V8. The Mark VII was 3,748 pounds, and Mark VIII was 3,757 pounds. The more aerodynamic, organic shape of the Mark VIII meant overall height was slightly lower than before at 53.6 inches, over 54.2” for the Mark VII.Īlthough the Mark VIII was larger than its predecessor, through the use of lighter materials like aluminum it weighed about the same. Overall width increased notably, from 70.9” in Mark VII to 74.6 inches on Mark VIII. Mark VIII spanned 206.9 inches in length, compared to 202.8” on the outgoing Mark VII. Other dimensions of the Mark VIII were larger in all directions, a stark contrast to the extreme downsizing implemented on Mark VI, a measure pushed further by the tidy proportions of the Mark VII. ![]() That was a notable increase over the 108.5-inch measurement of the Mark VII. Though it was technically a “separate” platform, the new Mark VIII shared its 113-inch wheelbase with the Thunderbird and Cougar. Ford attempted to deliver the same experience for less money with its MN12 coupes and derivative FN10 a lightly reworked MN12 chassis used exclusively on the new Mark VIII. In particular, BMW was on the mind of all domestic manufacturers in the Eighties as yuppies pursued status and Ultimate Driving Machine pleasure. An intentional move on the company’s part, the plan was to catch a more elevated customer than those persuaded by the Fox body trio: Ford Thunderbird, Mercury Cougar, and Lincoln Mark VII. Ford spent a lot of money and a lot of time on the development of the MN12 platform.
