I got my 4.30s today and I really want to try to put them in myself but scared to.
Gears are something that you want to have done professionally........
Do the gears yourself. Save the moeny . It is simple to do. Before I did mine I was super nervous and stuff but just follow a write up its simple. Here look at one of my olds threads read through the write ups.

Honestly if you have any mechanical inclanation you can do it.It was my first time.I have no gear whine at all. The most frustrating part is getting backlash correct. That is what took me a few hours. The rest was simple. Very simple. Make sure you have a place to get your bearings pressed. I always like to make sure I have all the proper tools before any project and have thourougly read all instrouctions. :beer: Pressing the bearings will cost you 20$ and dial indicator guage you can rent and a torque wrench. So you really dont need any special tools.Do it yourself and laugh at everyone when you have an extra $300 in your pocket! :banana:
I have all the required tools in the garage and still paid someone else to install my gears. I build 5.0 engines for people as a hobby and been very successful at it, but would still rather pay someone to do my gears...
For 99% of the people out there, paying someone to do it is their best option.
