LS vs Coyote: size, weight and swap cost

A proposed comparison from published figures (Speedway Motors' engine dimension chart and current listings):

	LS (e.g., LS1/LS3)	5.3 LS (truck)	Ford 5.0 Coyote
Height	28 in	34 in (truck intake)	27 in
Length	29.5 in	30 in	28.5 in
Width	24 in	24 in	30 in (DOHC heads)
Weight (dressed)	415–460 lb (aluminum)	440–460 lb	575–600 lb
Stock power	LS1 305–350+ hp, LS3 430–480+ hp	290–310+ hp	412–480+ hp
New crate engine	475 hp 5.3 LS crate: "a touch over $5k" (Speedway)	same	Ford Performance Gen 3 Coyote M-6007-M50C: $10,224.99 (90racing)
Supply	Millions made; last production versions 2017 (Speedway)	Most plentiful LS	Aluminum only; Mustang GT and F-150 since 2011; still in production (Gen 4)

Swap parts (current listings):

• Mounts: LS mounts run about $125–300 by chassis (PSI, ICT, UMI). The ICT Coyote universal billet mount kit is $270.
• Headers: Coyote swap long-tubes for 1965–77 Fords are about $740–950 (Doug's Headers). LS swap headers are similar per chassis (e.g., A-body long-tubes about $400–1,100).

Takeaways (Speedway): the Coyote is extra wide because of its DOHC valvetrain, so it's harder to fit in older Fords, while it bolts right in where a Modular V8 was. It's aluminum-only and loves to rev. The LS wins on compact size, weight, junkyard price and aftermarket support. The Coyote wins on stock power per liter and Ford-brand fit. Budget roughly twice as much for a new Coyote crate as a new 5.3 LS crate.
