[quote="Clint44"]The 2012 trikes will have a new 4L65E four speed overdrive auto to replace the TH350. It also looks like the ZZ4's days are numbered too as the factory is working on a 4.8 liter replacement. That engine with the optional cam kit really sounds nasty. Even though it makes more power,the fuel economy figures are amazing,high 30's at least.
Exciting things are coming,for sure.
Cannot agree more.These new LS engines are wonderful power sources. I have an -09 Chevy Colorado w 5.3 engine and it´s more powerful than any other "old" ,untouched small block that i have had and fuel economy is unbelievably good. The only "problem" is that it sounds like a sewing machine,but it can be fixed w cam kit.
