Things every car guy should know about engines

There are a lot of factors to consider when building a 1000+ horsepower engine: compression ratio, displacement, I vs H-beam connecting rods, what type of metal the rotating assembly is made of, fuel system, and other supporting upgrades and maintenance. In this video, I cover these topics in-depth as I pursue building one of the most powerful 4.6 Mustangs ever built.

I made a mistake at 5:39 where I talk about increasing cylinder diameter with a honing tool. While technically possible, it's a terrible approach as it'll take forever and will likely result in uneven cylinder walls. The cylinders need to be professionally bored and checked against one of the pistons (that will be installed) to ensure proper fitment/clearances.

[@Firion13]

Well what you said is true, there are some amazing honing machines out there now that do exactly what you said initially. You should look up some information and videos on the Sunnen and SV-10. It's a fully automated hone. It can detect cylinder board distortion and correct it itself leaving you with perfectly straight and round cylinders. It's amazing.

Just FYI, the honing tools that most shops have are for reconditioning the bores during a rebuild, not increasing displacement. They're basically just for getting the cross-hatch pattern back into the cylinder walls. Also for trans, the T56 Magnum is supposed to be a beast.

[@CG_Element]

I’m glad you’re building your 3v. I also have an 07 which I plan to build one day and I’ve always wanted to run a setup almost identical to what you have. Twin turbo, Manley connecting rods and such. When I first got the car I wanted to coyote swap it, but after attending mustang week in myrtle beach SC for a couple years, I decided I want to build the 3v, because it’s so rare to see a built 3v even at an event all about mustangs. All you see is coyotes everywhere and every 4.6 is bone stock. I don’t want to just be another coyote car, I want something different and that’s why I want to build the 3v and I’m guessing it’s the same reason for most other people who want to build theirs too.
