How much can u bore the coyote block

[Twinscrewgt]

I know some guys have gone .01 over. Can these blocks be bored .02-.03?

 

[Wnt2gofst]

If remember right livernois took it to a 306 stroker.

 

[Twinscrewgt]

Was that with bore size or stroke length?

Im curious about this as well.

The last thing I would want to do would be to stroke this engine, but boring out for displacement would be great.
Id imagine you'd have to sleeve it to get any real increase though.

 

[stkjock]

they are sleeved already from the factory.

the walls are pretty thin as I recall. I doubt they could be bored more then .020

 

[SteveP]

You can bore them .005 and .010

 

[Twinscrewgt]

Ok. Thanks steve!

Obviously. You have to have sleeves in an auminum block.
Most modern engines dont have enough meat in them to get much from a dry sleeve without weakening the cylinder walls significantly.

What I meant was punching it out into the water jacket and putting in a new wet sleeve.

I would be more inclined to make custom pistons with the wrist pin moved up inside the scraper ring. Should provide a fair bit of added rod length.
Or, if youre already sleeving, weld on a deck plate to get some serious added length. The only problem would be that the intake manifold, exhaust, timing chain, and god knows what else, would no longer fit.

Hearing a cross plane V8 at 10k would be very cool though. I know its been far exceeded with flat plane engines, but Im not sure how high anybody has reliably reved a cross plane.

the water jackets seem pretty weak as they sit from the factory. I was talking to Michael from L&M and Mike from Powerhouse last week at the NMRA event and got a small education on these new motors.

and BTW the new 5.4L blocks are not sleeved

Time for a custom billet aluminum block ?

which is expected to handle upwards of 2,000 horsepower and nearly 8,000 RPM

I'll wait to see if that is what happens

 

[KonaGT]

I have heard of the stock block breaking at 1,000 hp on a turbo setup

 

[LavaSlide]

I would like to see this kit in action. It does sound promising tho.

 

[Kingcrabb]

any idea on pricing?

 

[LavaSlide]

I have emailed them to get a price. I have not seen a reply as of yet.

Fill it with Hard Blok.

 

[KonaGT]

Fill it with Hard Blok.

What about the guys that want to drive it on the street?

 

[Kingcrabb]

i dont think 2000 is really that streetable anyway...
Maybe a 1000.
