its all good mate its all in the fun of it and I'm still going to fiddle

and my landlord who builds race motors basicaly big block v8s, laughed his head off at me and said anythings possible.

hell a 4y rebuild kit including sleaves can be had cheap enough so why can't i get creative, hell i don't care if it takes a year if i can get the 3 or 4 y crank to spin in a 5k block hell il go to town on the milling machine making shit fit haha. the ball and chain said keep it k so il build a big block k motor lol.

Yeah why not go for it mate, well done pretty inspiring stuff

hell even a 2lt k motor would be a tuff motor

Just bore put a 7k then? that would be pretty close to 2L.

my understanding is that the head is the biggest restriction on a k engine? Wouldn't want to go to all that work only to find out it will hit a brick wall. Pretty sure I read that darren untubbed's ke10 wouldnt make any more than 150 odd rwkw because the head just wouldnt flow it?

I think you'll get it, if you spend enough time on your knee pads at the machine shop. It would be quite an angry motor by the time its finished : )

 

Keep us posted ol cheeze, this will be an interesting read =D

I also think this project has merit. Do it. Post pics.

2Y and 4Y motors have a shorter stroke than a 7k. :hmm:

 

7K's have a wider block (compared to 5k) to accommodate the increased stroke.

excuse my ignorance, but why not just use the complete 2y/4y engine? with whatever gearbox came in the van?

 

apart form the academic exercise, i don't really see the point in trying to combine the two?

 

I'm open to corrections of course.

I got a 2Y engine in the shed! time for a project me thinks!

Ability to use K-series mounts perhaps? Although if you're putting that much effort into building an engine a couple of engine mounts are hardly a deal breaker...

my machine shop is accross the road and i pay in burbon haha his been bildign race motors for 40 years so machinign isnt an issue and why bother doing it because i can and wheres the fun in just dropping a 4y in a rolla when u can spend weeks building a one off k motor and have a ball

is stroking the motor the same as shaving the block down?

no
