Re: Popularity of GM LS crate engine vs Ford's
If we are talking NA carbureted OHV crate engines, Ford and Chevrolet both offer many options ranging from simple swap and/ or street performance to all out competition across many displacements. Neither has a clear advantage over the other, not in size or power per displacement and even price is very close, although Mopar typically costs more. You can buy or build a 427ci Ford / Chevy engine and even a 426ci mopar stroker small block stroker engines (starting with 351 / 350 or 360ci small blocks respectively) that all make massive power, well North of 500hp and far more torque too and ALL of which package in an equal space of a small block OHV V8. More or less. Even Ford's Boss mod motor is quite the package offering North of 500hp.
If we are talking modern replacement V8 engines in the last decade or so that include fuel injection, etc…….then the discussion gets complicated, not unlike comparing production V8’s from all the above. But GM does have some advantages there, especially in scale…..they offer far more products that use a V8 than Ford does. Camaro, vette, CTS, G8, SS, truck, etc. But Ford is hardly a slouch, with their 5.2L and 5.0L that will soon be upgraded and more than capable of taking on anyone in a fight.
Every sub-$50,000 car on the market will have to answer to the Ford from now on, no matter what badge it brings to the table.
