K Series Block

Featured Replies

On the weekend, while tinkering with my 5k, I got thinking???

 

With the K series engines, 3k, 4k, 5k…

 

With the heads all being different sizes, wouldn't the blocks all be the exact same???

 

:D

there's also deck height differences, bore size, crankshaft clearance, sump pattern. the engine mounts are all in the same spot, but inside the blocks are far from the same
