(up to 2.5 hp/cu. in.). [34]
In addition, Toyota examined the engines of Kyle Busch and Martin Truex Jr. after their cars experienced engine failures during the race. [113] At the 2022 Autotrader EchoPark Automotive 500 at Texas, Cody Ware survived a hard crash, colliding with the turn 4 wall before violently hitting the pit wall. [ 114 ]
Other manufacturers may modify the engine after it has left the Toyota factory but the engine still keeps the original Toyota designation.

[3] 1994 was also the final year that V6 engines were used in the Busch Series, as many short track series had abandoned six-cylinder engines.
Each team may build its own cars and engines (per NASCAR's specifications) or purchase cars and engines from other teams. The cars are powered by EFI V8 engines since 2012 after 62 years using carburetion as engine fuel feed with compacted graphite iron blocks and pushrod valvetrains actuating two-valves per cylinder, and are limited to 358 ...
One popular idea was to use 231–275 cu in (3.8–4.5 L) six-cylinder engines; instead of Cup Series' 358 cu in (5.9 L) V-8s. [5] [6] [7] In 1989, NASCAR changed rules requiring cars to use current body styles, similar to the Cup cars. However, the cars still used V6 engines. The cars gradually became similar to Cup cars.
The trucks of Lance Norick (No. 90) and Terry Cook (No. 88) racing in 1998 Ford F-150 Chevrolet C/K. The idea for the Truck Series dates back to 1991.
