Will an LA-360 bolt in where a LA-340 was?

Thats why I horded several standard bore 340 blocks 25 years ago. Hell, they were pricey and hard to find back then. If your building from the block up a 360 is fine. I prefer the short stroke of the 340 but a 360 can be built for some serious power.
You can make up some spacers for the mounts but its not much needed. If I recall it usually only takes 2-3 washers. However, if you have 340 mounts now I think they should bolt right on the 360 block with no changes. Its the 273/318 that had different ears if I remember correctly.
