I don't see an engine forum so I'll post here. 4.7 Q
 

They're using MDS on the 5.7 hemi. Do you think it would be good on the 4.7 also? Makes sense for a second v8 in the magnum. I'd rather have a small v8 to a 6 in one of those cars. Also in the dakota and durango too.

Don't get me wrong, power wise the HEMI is king, but with $3 gas, dropping a litre and using MDS could save more gas.

Add a starter generator so you can shut off at stoplight and such and I think you'd have a real winner.

Just my half drunk 1am musings...
