Mopar 4.7 Stroker

Postby Plechtan » November 2nd, 2009, 7:24 am

Here is a quote fron the Mopar Performance press release for SEMA

"Mopar will also introduce a new 4.7-liter I-6 Stroker long block, a powerful upgrade for the 4.0-liter I-6 made famous in Jeep vehicles built from 1991-2006. Because off-road enthusiasts appreciated the dependability and performance of the previous 4.0-liter engine, Mopar developed a more powerful engine that delivers an expected 265 hp and 290 lb.-ft of torque. The engine will fit in any Jeep vehicle previously equipped with the 4.0-liter I-6 engine."

Looking at the 4.7 recipe on Dino's site, he suggests different injectors and a larger Throttle body and projects 275 HP vs 265 quoted for the Mopar. I wonder if the engine will come with a reflashed PCM? Anybody going to SEMA that could drop by the Mopar booth and get mor info? I would guess that they would have to be emissions compliant, or maybe they are selling it for "off road use only"

I got an Email from Lee at Hesco, he says that ATK got the contract to supply the engines to Mopar.

Went to the ATK website, their warrenty was for one year 12,000 miles. So
if the Mopar 4.7 strooker is 3 years 36,000 miles, is it worth the extra $$$.

Like Tommy Boy said, "...they know all they sold ya was a guaranteed piece of shit. That's all it is, isn't it? Hey, if you want me to take a dump in a box and mark it guaranteed, I will. I got spare time.". My Titan had a warranty too.

At the price they are asking I doubt they will sell many of them, especially to a customer that does his research.

So does $4700 get forged or cast? Stage 1 or 2 cam? If i got forged piston for $4700 and a warranty that price would be toooooo bad.

For that money I'd rather have HESCO build me a stroker at least I'd know they'll stand behind it.

Mopar's Marked up the ATK by $1800 dollars (comparing retail prices) if you adjust this for the large wholesale volume discount Mopar gets from ATK then it's probably about a 60% markup... Talk about bending people over...

$1800 dollars is a steep price to pay for an extended warranty. Another $900 and you could have two strokers with 1 year 12,000 mile warranties.

Interesting.. I wonder what injectors they recommend. I also find it interesting that they use a HV oil pump.

Regardless of what Mopar put into their 4.7 stroker, they should have done a lot better than a mere 290lbft of torque at the crank for $4.7k.

Isn't 290 what the 4.7l v8 came with a few years ago? Isn't that reasonable for an engine with a warranty?

If you want maximum power you can always fit an even bigger v8 in there!
