Best way to proceed with improving up 427 Windsor street setup

Ace, you can struggle with where the horsepower you have lost may have gone and you might even get your mileage up into the low teens. You will spend considerable time and monies to get fuel injection in the car and properly tuned. When you are done you might get to 450 RWHP

Imagine for a moment how your 03 Cobra would have felt if you could have taken 1500 lbs out of it. You had a Blown 4.6 w/a KB on it, right? Pretty impressive, right? Well you can do that with this car that is 3/4 ton lighter! You already said you don't care about the under hood originality so put in a blown 03/04 Cobra engine (it does have the right DNA).

As you already know from personal experience you will go from 300/350 RWHP to 600+ with lightening fast throttle response and 20+ mpg, but again this is not new ground for you — you have already been there. Remember that broad flat torque curve the engine had and the bottom end blast? I bet you miss that! Now put that in a 2300 lb car!

BTW if/when you do it, polish the valve covers. When you open the hood it will be wall to wall blown and injected Cobra — with the blower front and center! The visual is stunningly similar to the 427 SOHC powered cobras except this engine is way lighter and easily as powerful if not more so.
