A 5.4 is *technically* a stroked 4.6. They share the exact same pistons. Stroking a 4.6 and staying N/A brings the exact same breathing problems that the 5.4 has with the exception of the extra weight on the nose. Just some food for thought. A comparison done a few years ago using completely stock parts and staying with the stock compression ratio, the 5.0L stroker LOST 17 RWHP and saw a 12 RWTQ gain. The power/torque band was moved lower in the RPM band. The 4.6L made more RWHP and RWTQ after 3500 RPM. Personally if you want an increase in displacement with desirable gains especially if staying N/A with a modular V8, then the ONLY way to do it is with a larger bore. Even though I have a N/A Big-Bore 4.6L( 5.0L ), it would be far easier to see a gain in HP with a SC and it is far more cost effective.
Sorry if I was wrong about the cam profiles. I was just going off of what someone else told me. The owner of the V10 Stang did tell me he needed a better performing cam. Pearl02.
ahh...never mind,...I was just trying to get across that not everybody has the same goals and in some cases a 5.4 might not be a horrible choice...but I suppose the interwebz isn't the best place for suggesting something different than what "everybody knows"
Don't stress it man. I'm not dogging on you for thinking outside the box. I'm just making sure anyone thinking of doing it is aware of and has all the variables covered.
It's only taken you 4 years. After you realized how slow your 5.4 2v was, you have now changed the game. Good luck.
im not sure i can gear or boost mine enough to run faster than the mighty Z. you win. no way a turbo 4.6 4v can run faster than 7.66.
You crack me up. You'r comparing a tubular front end/coilover, power steering delete turbo car to my car with 2 mods in full street trim. Haha, you're a funny guy. I get 30-31mpg on the highway, and I will be going much, much faster than 7.66. If you want to compare your race car to my street car on 18 inch tires, then so be it. Sorry, was that a 5.4 3v NA you had that you could not get out of the mid 8's? Unlike yourself, I appreciate all cars. My two track buddies actually both have gt500's. Here is Mark's car, same name as myself. http://www.youtube.com/user/snakeracerx#p/a/u/0/-dt4F4zLI3Y He has taken me out in the 2 events we have ran in. One with 900hp(Mark), the other with 1000hp. Full street cars, nothing removed, on the stock 18 inch wheels. Unlike yourself, they seem to not care what car somebody drives, and have a lot more respect for other vehicle owners. To each, their own. Enjoy your car!
