Help on deciding my engine

[1BAD72C10]

Ok so I am in the planning stages of my build. I know I am getting ready to do a tranzilla t56. What I am trying to figure out since the engine builder I was going to go with doesn't seem reputable after doing some research. Anywho I want a tt motor. I love big blocks but was wanting some of you guys opinions. It will have to be efi as well. What I am wondering is do I do a 540 tt or an lsx tt motor and what configuration. I would like to have around a 1000 hp daily driver. So any advice from some of you guys or gals would greatly be appreciated. Thanks, Brad
