360 Core Questions
273-318 have the same mounts, 340 -360 have the same maounts, but not like the other smaller engines. You can use a 318 mount with washers to take up the extra space. There wider. ONly one side. (I keep forgetting which side........soooo stupid, but ..)
360's have different oil pans and crank journal sizes. Truck engines have a 3rd kind. Rear sump. No good for cars.
64-66-/ 273's have a different intake attaching angle and smaller 5/16 hardware. (I think it is.....help on that please)
273's valve limit is a 1.88 with a bore notch. Otherwise most everything else can swap from one engine to another.
Small blocks must use small block trannys. 360's are extrnal balanced and the 1 year only 340. A '73.
