First bit of advice right off the bat.
If you plan on buying CPP engine perches buy the new redesigned CPP sheet metal engine perches and the poly motor mounts, you will be real glad you did because the clearance for exhaust is much better, so much better infact that you will be able to use the stock camaro exhaust manifolds without modifying the engine perches.
Also if your AC bracket is on the lower RH side of the engine don't buy the 3" forward LS Swap Engine Mount Plate because it wont work on our trucks, the correct one is a 2" forward plate which I can provide the specs for and you can have it fabricated locally.
To counteract the 2" forward adapter you just move the engine perch 2" towards the firewall from the stock V8 position.
