Here are the thought processes or questions.

5.3 whipple charged z71. 80e conversion or 4l65 I only want an FLT tranny there are no others that I would consider.

The conversion kit can be seen at the link below

the 65 at flt is below

Is the speed eng 4l80 by FLT? For the money which one is gonna be better and live longer.

I also thought seriously about changing from part time 4 wheel drive to all the time awd by using a transfer case from an gmc c3 truck. Would I have to have any other parts besides the transfer case to install this. Also would it act like my truck does now on pavement in 4wd?
I eventually want to upgrade to a big motor and want the trans to be able to handle at least 500 rwhp.

Any thoughts or suggestions would be appreciated.
Also I tow a 17' enclosed trailer at least 2 times a weak so reliability is important.
Thanks
Jake
