Look pushrods... aren't they something.

 

How many sizes are there for the K motor series? I've measured the few I have so please do the same for the good of the forum's FAQ.

2K(import) -

3K(early) - 172mm

3K - 175/176mm

4K - 186mm

4K(with lugs) - 180mm?

5K(solid lifter, D-Dish piston) - 180mm?

5k(hydraulic lifter, D-dish piston) - 150mm

5k(hydraulic lifter, shallow dish piston - 156mm

7k -

 

A12 - 152mm

 

PS: no i'm not a kiwi though I did source my apparently false information from Club-K.

You are way overcomplicating things.

 

You have flat top (well really shallow O-dish for 5k)and D-dished (Reverse Domed is the correct term) with the 4k/5k motors.

 

I would have made the list more like:

 

K

3k bigport

3k smallport

4k flattop

4k dished

5k flattop

5k D-dish

7k

 

2k aren't in anything australian delivered.

That's nice to know...

TS- twin squish (a pretty much meaningless term) = W- with head lugs

typo, got 5k pushrods back to front.

Are you a ex kiwi?

 

If so on cluib-K everyone knows what a "twin squish" is.... here not so much.

Solid lifter 4k and 5k dished with lugs should be 180mm overall, as the heads are 6mm shorter than the normal ones.

 

5k flattop (no lugs) with factory solids would be the same as flattop 4k's at 186mm.

 

K, I've got some around here but no idea where they are after our recent move. I'll keep an eye out.

Are 5k dished engines solid or hydraulic?

Mine was hydro
