Even if you bought a complete engine, there are some mandatory aftermarket parts you need to buy for this swap.

To fit inside the Discovery, we need a very low profile oil pan. Without it, you run the risk of the from differential smashing into the oil pan.
The Holley 302-5 is the oil pan with the most front clearance possible. It is so low profile, that you need to cut the original windage tray to fit. This is the real deal, and we can attest to the quality.
If your engine did not come with a windage tray, buy one here. Part GM GENUINE 12611129.
This is a low-cost copy of the Holley 302-5, you can find many on amazon. Look specifically for "302-3". The 302-1 and 302-2 are not as low profile.
We can't speak for the quality, but we've seen reports of low quality internal finish, and slight fitment issues. You get what you pay for, but many have made it work fine.
Just like the Holley 302-5, you will need to modify the original windage tray. If your engine did not come with a windage tray, buy one here. Part GM GENUINE 12611129.
To fit between the frame rails, you need low profile exhaust manifolds that are tight to the block. Especially on the driver side, because our engine mounts push the engine towards the driver side as much as possible.
This is our top recommendation because the location of the collector very closely matches the Discovery 2's Y-pipe. With this exhaust manifold, you will only need minimal exhaust modification to connect the manifolds to the y-pipe.
If you are strapped for cash, you can save a benjamin with this option from summit racing. However, these manifold dump further back. The Y-pipe will need to be heavily modified. You will be working in a tighter space when connecting the y-pipe.
Now to really save some dough, you could buy only the left side manifold from Speedway, and use the original manifold that came with your engine on the right side. This is also a good option if you want to reinstall the EGR which connects to the right side manifold.
Our power steering bracket is designed to work with a GM Type II pump. It fits perfectly without any fittings or adapters! You may use any GM Type II power steering pump as long as the inputs and outputs match the stock corvette pump. Do not get a pump with AN fittings.
You will need a power steering pulley installer tool.
