      If you have the accessories from the 5.3 you should look into this conversion bracket:
      http://www.ebay.com/itm/LQ-LS1-Truck...1c4a96&vxp=mtr

      Otherwise you have to change all the accessories except the alternator and it will need an F-body bracket to make it work. If you do change the accessories to F-body you will also need a f-body crank pulley.

      Other than that off the top of my head you will also need
      LS1 intake manifold
      corvette fuel rail if you want to use a fuel return line
      oil pan
      windage tray
      oil pickup tube
      dip stick and dipstick tube
      motor mounts
      wiring harness. the truck harness will work but look horrible f-body is better
      pcm
      radiator - there is a steam tube coming off the heads that plumbs into rad
      steering shaft
      gauge cluster
      trans and crossmember
      cradle

      This conversion chart was in an earlier thread:

          You can check out my current project
          http://forum.camarov6.com/showthread.php?t=104970

          It CAN be done cheap if you search around and take your time.

          I highly recommend using search temptress for Craigslist: www.searchtempest.com/
          and
          www.car-part.com

          I haven't gotten to any labor yet but so far my parts total...

          1,900 Mile Engine (not even broken in): $900
          LS1 Accessories & Brackets - $550 shipped
          Wiring Harness: $300
          Complete K-Member: $200
          Oil Pan / Windage Trey & Pickup - $200ish
          Transmission - $400

          After all the LITTLE stuff it's ganna come down to about $3,000 in parts BUT we have a brand new motor and rebuilt transmission too... so it just depends on how you shop.

          I'm not 100% sure if that relocation bracket is going to work btw, I though there was a reason the F-Body's power steering pump was located where it was (due to the long steering linkage or something like that.) Do some research before doing that, if it works though congrats because it will save you ALOT of money.

              How hard would it be to convert it from an automatic to a manual?

                Re: 5.3 Vortec engine

                Wouldn't be too much harder since you have to replace your stock V6 trans anyway, but you will need to clutch, pedals, new center console, clutch reservoir and a few other things...but the M6 is not a cheap transmission so be prepared to spend $$$

                  Will I need to do anything with the rear end? How do I know if it has the y87 package?

                    It will say Y87 on the RPO codes on the Driverside door label. Open the door and there will be a label on the inside of the door - it will say Y87 if it is...but there are some F-Bodies, primarily Firebirds that are Y87's and havent been marked. Mine is as I have 3.42 gears, Z28 rack and a performance exhaust.

                    The easiest way to tell is just see if your car has a dual exhaust from the factory. If it does then you most likely do.
                    Y87 cars also shift into 4th gear just above 40 MPH as well.

                      I would find a 4.8 or 6.0 and build it for boost. you can use a v6 rear end. What gears do you ultimately want? if turbo, 3.42s or 3.23s would be perfect. You can get those in a stock rear too.

                        just curious why would a 5.3L be a bad candidate to boost? especially over a 4.8L? Not to say a 4.8L can't be a monster under boost and they're cheap too but why did you opt for a 6.0L when they cost about 4 times more than a 4.8L?

                        Meanwhile, a 6.0L is a mean motor even N/A if you can get your hands on one.

                        L92 Heads and a good cam and you're already knocking on the door to 500 Flywheel HP.

                          Ported Throttle Body: Worth It?
                          by CamaroZord
                          Hello V6 folks.
                          Wondering if any of you have printed their throttle body. Is it worth it? What difference have you experienced?
                          Thank you....
