Click to expand...


any motor CAN like boost... 03 cobra stuff has a forged bottom end and really allows for the increased power. For what you will spend on a 03 cobra motor and wiring, you can build a 5.0 based motor to hold the same if not more boost than a 4.6

This is the problem:


The dohc motor is so dang wide that it just doesnt fit well in the engine bay. With a MII it will fit no problem. By notching the towers, you will NEVER get the valve covers off without pulling the motor. Headers will be a *(*#$$ too.

Its all about preferences... if you want to do something different, do an 03 cobra motor. Its going to cost a lot more than you think and its going to take 3 times longer than you think.

<----put a sohc with MII in a 66
