Hello, I have 2005 Mustang GT car supercharged with edelbrock or supercharger and methanol injection. I threw a rod in that motor do to detonation, my question to you guys is what would you recommend the route I take to fix my car. I have a running and driving 1997 Lincoln mark with a 4.6l 4 valve, I also have 4.6 liter 2 valve out of 04 Mustang GT. Which motor should I run? I was going to use the block or short block of the 04 with my 05 3 valve heads, supercharger but I was wondering If can put the 4.6 4 valve in my car what I would have to do to use my supercharger as well what are your recommendations for ECU wise to run the 4V I do have a shop I any of your help would be appreciated. I also own a twin turbocharged 95 SVT cobra that has a standalone. kind of a pain in the butt. So what's the easiest way to control your recommended option? TIA

If you have the supercharger then I would stay with a 4.6L 3V and make sure you keep it from detonating. With a replacement engine you could go with forged internals and lower the compression to hedge your bets on detonation.

If your 3V heads are still good, you can bolt them onto a 2V block built with forged rods/pistons and an upgraded oil pump. You can reuse your 3V crank if it's undamaged.
