I've been reading articles about this engine and the new trubo diesel they are workign on for the last year and a half. Ever since the HEMI entered the picture it put both chevy and ford on the offensive to compete. Chevy already had an abundant engine supply to choose from and as usual, ford didn't. It should be interesting. I would imagine something in the 350 ci size to eventually be put in the mustang as a standard engine. Detuned ofcourse.

Heres my problem with a bigger engine. The car will undoubtedly weigh more, maybe a lot more. Just like how the GTO and the Hemi's are already big engines yet are the same speed as the GT which has a smaller engine and lighter body.

Id expect, due to all changes weighed in, a 6L mustang will push 13.2 stock, maybe 4300lbs.

You gotta realize that cars will not continue to get faster. As engines get bigger so do cars and the times generally will stay the same.

^Exactly.

not a chance of a 6L being the stock engine for a GT, it will be too expensive and they wil lose most of their market share - GT's now only account for something like 20% of mustang sales give or take, Ford knows the money isnt in the big engines, the sixxers is what made them money

Good point.... not only that but I'd take a fine TUNED 4.6 that is also capable of supporting more hp on the STOCK block than a big piece of garbage 6 liter. BMW can make over 400 rwhp on a 4.0... certainly Ford could make the 4.6 A LOT more efficient.[:@]

Dont forget the new CAFE standards that are proposed. This is the reason chevy is cutting all their rear wheel drive cars in development. It was already to late for the camaro and G8so you will see them soon.

It pains me to say but I think you are much more likely to see the new generation of turbo 4 and 6 cylinder engines Ford is developing before you will see an increase in displacement. These engines would be lighter and produce about the same power as the current engines with improved fuel economy.

Just my 2 cents.

If Ford EVER turned the Mustang into a turbo 4banger or a v6 I'd never buy another mustang for the rest of my life.

Done that, been there: SVO

It wasn't bad, just that the 5.0 could produce same power and more torque for less money.

Wierd article.

Why no mention of the Boss 302 and 429 engines of the 60's and 70's?

Also, isn't this new iteration of the boss engine supposed to have pushrods?

thats ABSOLUTELY not true, not in any way. the "bigger" in your terms (liter capacity - cubes) doesn't mean hundreds of pounds more in the engine, NO. the only thing that changes is the block, and internals. making the engine looks in the outside basically the same. Its like saying ... the vette Z06 since it has a 7.0 liter (427cu) engine it now weights 4,200 lbs ... no. It weights the same as the porshe carrera GT, 3150 lbs !
What does count in weight is the block if its made by cast iron or aluminum, and if its made by aluminum the engine will weight about the same as the one we have right now.
