Piston speed doesnt even reach 3600 until around 7800 rpms...




Once you start making high HP/TQ on a square engine, recip weight becomes a factor. A big enough of a factor that it could be what holds the crank together since it's now the weak link in the shortblock.

Its not that square when you run 92mm bore...
I'll never have a 3.0L block, but my 2.5L with darton sleeves comes to 3.2L. I am working on this project as we speak. I have some eagle rods that will work for now. I had to resize the wrist pin whole and run a .030 under bearing, Its 5.400 long with a small block chevy journal, with the .030 bearing it makes it fit the dura crank perfect. For 475 this was a whole bunch better than 1000. The sleeve kit installed is going to cost me 1000. Plus 655 for custom pistons, and total seal rings. You can get the arp main and head studs because I know what length to get. They have the studs just not in kit form. I'll run this with my turbo set-up that I'm finishing up right now and make around 450 to the wheels. Eventually when the EEC-V AEM ecu comes out I'll put one in the car and get rid of the stupid MAF meter.

I am an AEM tuner if you hadnt figured that out. I tune my fathers mustang that makes 1900hp. Its a Fun Ford Weekend Street Outlaw car with a 101mm turbo.

So like my first question. These are going to take a year to make? What about doing a group buy, with a set minimum of 5, so those who plan a build don't have to wait so long.

Yea daddy`s toys are nice arnt they? 6061 or 4340. Titanium is a useless alloy in high loading applications. Thats the reason its most mainly found on high rpm light load n/a engines.
