The main application of uneven firing intervals is motorcycle engines, such as big-bang firing order engines. Examples of odd-firing engines are most four-stroke V-twin engines , 1961-1977 Buick V6 engine , 1985-present Yamaha VMAX , 1986–present Honda VFR 750/800 , 1992-2017 Dodge Viper V10 , 2008-present Audi/Lamborghini 5.2 V10 40v FSI [ 7 ...
The top-oiler block sent oil to the top center first, the side-oiler block sent oil along a passage located on the lower side of the block first. All FE and FT engines have a bore spacing of 4.630 in (117.6 mm), and a deck height (distance from crank center to top of block) of 10.170 in (258.3 mm). The main journal (crankshaft bearing) diameter ...
The big-block engines initially used a forged crankshaft with a stroke of 3.975" for the 1965-1967 425 and 400 CID versions; starting in 1968, both the 400 cu in (6.6 L) and the 455 cu in (7.5 L) big blocks used a stroke of 4.25 in (108 mm), with crankshaft material changed to cast iron except in a few rare cases.
