Gear drive
No, it's not a POS at at all. it just needs a little work to make it perfect is all. It's not a direct bolt on. Search on the forums here, there is a lot of good information on it that myself, Mad Dart, and a few others have contributed on this excellent piece. It has been run in the engine masters too.
The gears are of a very good hardness and quality of steel believe it or not, and the idler gear bearing is freaking STOUT.
Search on it here and read. you'll pick up all the details.
I will give one bit of advice. the one thing on it I would call a design flaw is the right hand threaded idler gear. Unbolt it and put some green, or red locktite on the threads, then torque it back in. Or you can do what I did and cut a keyway in the back of the mounting plate to lock the bolt in place.
Geardrives are stigmatized because they transfer crankshaft vibration. but given all the nice modern parts we have now, this really isnt much of a concern. Some will of course disagree. It's a free country.
I should be starting it up very soon. I'll post it here so you cn hear it...and that's another thing. This geardrive has a pleasant whine. It's not the piercing shriek like a milodon. And this isnt to say the milodon is **** because it isnt. It all depends on what you want. The milodon bolts right in after drilling a hole. This geardrive needs a number of little tweaks, but I think given the price, it was definitely worth figuring out what was required to run it.
Here is mine installed on my 408.
