Is it possible to put 5k crank, rod and pistons into a 4k block

Moved to k motor discussion. I dunno the answer but give it a google;)

don't 5k's use a larger piston?

don't 5k's use a larger piston?

 

sure do

BOOM! I'm the man.

5 K crank os the same as a 4K crank. 73mm stroke.

 

Standard 4K bore is 75mm, 5K 80.5.

 

I had CB23 Charade pistons (standard 76mm) in a 3K, which from memory we took out to 78mm (2mm oversize?) at which point we got scared.

 

I believe you won't get 80.5's in a 5K.
