Default fox to TTLSX

I want to build a TTLSX fox just looking for the basic stuff. I want to know what motor mounts to get. I want to punch out a LQ9 to 427 with forged guts, mild cam ,TT and meth inject, Tuned on E85

The baisc stuff I need to know is how to get the motor into the fox

1- Is the AJE kmember all i need to intsall the LSX?
2- Will a Th400 fit under a fox
3- Do I need a adaptor to get the TH400 to work with the LSX?
4- Could I just get the AJE motor mounts for the stock k member? (instead of the AJE k member)
5- What kind of converter will I need? (Needs to be a big stall with a trans brake)
6- How big can u punch out a 5.3?

All your questions can be answered by using the search. There is plenty of info on here about the swap....

1-The AJE k-member is all you need for the motor to sit in the fox...
2- Yes, fits like it was meant to be there. I have a 4l80e in mine with no problems.
3-No adapters needed, just a certain converter I believe(Auto Trans section has tons of info on this!)
4-No
5-not sure
6-you do know a lq9 is a 6.0L right?

can punch out 5.3 3.78 bore to 3.905 bore if need.
but not recommended for psi. street n/a is ok.
3.905 with stock crank =347ci
but will need to get crank rebalanced for whatever piston and rods used
