I think it's no different then all the marketing we've seen for any other engine in the last 20 years.
IT'S A SALES TECHNIQUE. As simple as that. I bet when we look at it down the road in 5-10 years, we're going to start seeing them die. No doubt.
Chevy 305? PSH that motors not worth playing with IMO. It's easier to find a 350 that has a similar weight, less restrictive heads, no emissions ETC.
The Chevy 3.1, and 3.4L were TERRIBLE MOTORS. My mothers '00 Venture had it replaced under warranty at 30K miles because of a recall on the top end. @ 150K miles we had the heads off replacing the weak intake gaskets that would fail and leak coolant into the runners. We did it also at 200K miles. It got 2 water pumps, but I can't blame that on the motor really... This was on the 3.4 motor.
My sisters '96 Monte Carlo with the 3.1 had the exact same issues. We did intake gaskets when we got it from my Aunt. A few months later, the head gaskets said ADIOS. Other then that, it hasn't been too bad. The car wants to die, but we're trying to keep it alive until she can replace it.
I hear people complain about their cars all the time @ Autozone, and most of the people having issues are the same ones that buy $9 oil changes. Occasionally I'll get the gung ho car guy that comes in and buys Royal Purple and K&N for his cars, but the majority just don't give a fuck. Put in Autozone oil and if it leaks out, put in more.
This new Ford motor needs to prove itself before it gets any respect from me.
