1) The frame mounts will have to be changed to Camaro. There are two different mounts that Chevy used. You can see the diffrences here

When you get the motor mounts. Make sure you get the ones that go with the frame mounts you get.
Remember when you remove the Pontiac frame mounts, that they are mounted with the A-Arm bolts, so caution when removing them

2) The starter nose piece will need to be changed, or just get one for SBC

3) For the wiring. If you are planning on ever returning it back to ORG. All you have to do is just extend your wires you have now, to make it to the new spots. (Coil,Starter,Alt,Temp & Oil sender if you have them.)

4)For the trans if it is an auto, they make adapters plates

5) You will need mounting brakets for the Alt,P/S,A/C that fit SBC. Also the crank pully, and Dist.

6)Fan shroud for SBC Camaro

7)Depending on what you going to do for exhust. Some long tube headers will interfer with the steering linkage.

8) Maybe have to reroute the fuel line.

9) Depending on how low you want the front to sit, I put SBC Camaro front springs with one coil cut on my 69.
