V8 K-Frame Question
If the K frame is a v8 type then all you need to mount a 340 or 360 are the correct motor mount engine "plates". The K frames are the same regardless of whether it was a 273, 318, 340 or 360 original application. It might also have the later spool mounts which are actually better than the old biscuit mounts, the spool mounts are failsafe design - if the rubber wears out the motor is still locked into the K frame. In fact it doesnt really matter what K frame it has - Schumacher makes the pieces to put a small or big block into a /6 K frame or small block K frame, spool or biscuit type mount. If the bodies good buy it if you like the car, it can all be adapted.
