Very little interchanges with the car engines except block.
It has much higher cylinders with a wider intake by about an inch or more.
The exhaust manifolds look similar to a 340 but larger. Bigger water pump and different location for it. Several other distinctions are easily observable.
It does have a windage tray that you can use on regular B engines. I have scrapped all mine years ago.

Hi John, the heads and mani are different sometimes but the block has the same deck with thicker cylinders, all other parts interchange with any raised block, they are commonly used in Max Wedge stockers. The 361s were used for industrial use also but are less common.
