-What cam should i go with to make between 500-550 horse at the crank?
-Hope to be running a t-56 tranny.
-what fuel rails and injectors?
-finally what all do i need in terms of wiring harness and ecu for this all to work?
- also, anything else i may be forgetting
Any advice and/or suggestions would be amazing.
thanks in advance guys,

**Depends on if you are going with drive by wire or cable. I vote for dbw. If so...you can get the truck motor, than a LS1/6 Corvette intake and you can still use the dbw TB that may have come on the truck donor.
-What cam should i go with to make between 500-550 horse at the crank?
**I would contact Comp Cam - discuss your gear ratio - transmission, and expectations.
-Hope to be running a t-56 tranny.
**This would make it wise to buy a LS donor that comes with the transmission because piecing it all together is a real pain and can get more expensive than just having bought a LS1/2 with T56 from day one.
-what fuel rails and injectors?
**Stock rails are fine - but that kind of hp will you will want some 35# or so injectors. SLP can also set you up with a cam and injectors together.
-finally what all do i need in terms of wiring harness and ecu for this all to work?
**I suggest you get a painless harness - and run on a 0411 PCM (especially if you go dbw)
Oh...if you go DBW, you will need the pedal and TAC module out of the donor - unless it is a 2006 - up LS with a 52 tooth wheel and the newer computer.
Confused yet? LS1tech has great info about this swap as well.
