Reply to "4.6 3 valve install. 2008 gt. Anyone done one?"

I did have a Teksid DOHC 4.6 with the ZF in my car when I purchased it. It was a dog in the power department. It was beautiful to look at, started every time, had power steering -- but man, that engine did not have the power I was looking for.

If you want to do a mod motor and not expect serious horsepower, then fine, I understand. Just do not expect the 4.6L motor to make more horsepower than the 351 motors. I remember my uncle saying something a long time ago when I broached the subject of my 16 valve 2.0L inline 4 cylinder Triumph Dolomite Sprint engine -- ".... there is no replacement for displacement...." I hated to admit it at the time, but now I can honestly say that he was right, and I was not. It is a lesson that I will never forget.

So again, it depends what you want to do with your car but do not let anyone tell you that the mod motor is this huge horsepower hi torque thing, because you will be disappointed. Now if you add a supercharger or turbos to a mod motor that is something different too, but we are definitely moving into a different price range with that stuff too.
