World Block Size Question

World Block Size Question The standard 9.2 block has been used with 4.125 and even 4.25 strokes. The Warhawk has a 9.7 deck. Can it handle a 4.5 or larger stroke?
On the block it self the specifications say .3" aluminum and .1" liner on the bores. Could a Nikasil coating be applied directly to the aluminum?

The Warhawk tall deck is 9.800". A 4.500" stroker will physically fit the crankcase and clear cam and block. However, until we mock-up this combination we do not want to speculate or spread disinformation. We believe an external oil line may be required but we're awaiting finish-machined blocks to test. We have the rotating assembly on hand for mock-up. We feel that 481 inches is quite suffient to produce 1.5 N/A power levels.
We have no experience with nikasil, nor the desire to experiment with it. We leave it up to experienced builders to follow their ideas and create exotic combinations.
Right now, we'd just like to get the damn parts into customers hands.
Info on this combination will be disseminated here when we produce the data.

the Warhawk block looks very nice! and 481 would be great!
as for Nikasil lining, i have heard about some of the biliet CNC machined blocks have used Nikasil and had really good sucsses even in racing applications!

Just add the difference in deck heights...

All of the deck height didn't necessarily go into the sleeve. Although, since the cam wasn't raised or the oil pan rails widened, it is more likely it did.
The World block has pretty think walls (.3" Al + .1" sleeve). If Nikasil eliminates the sleeve, it could have a 4.35 bore.
A 4.125" stroke is readily available for the 9.2" block. And a 4.25" will fit. Add 1/2" and you get 4.625" or even 4.75". To gain extra clearance you could reduce the rod journal to 2, 1.88, 1.85 or even 1.771.
Put that together, and you get big block displacements of 525 to 565. In an package only slightly bigger than an LS1 and weighing less than 500#.

There is only one company I know of that does Nikasil in the US, they did a BMW M5 block for us recently, it turned out pretty good and the cylinders are tuff as hell, it seems to work really well, certain OEM blocks use it. I've thought about doing a Nikasil block as well...just haven't had time to mess with it yet. I was going to experiment with a LS2 block first to minimize expense.

as i said there are racers running them on billiet LSx bloks! also the motor bike guys have run them for ages! they are strong! but if you cook a piston, and it rips through the coating it can mean bye bye block, but then it can on any engine!
also you can have the Nikasil re-coated if wear becomes a problem!
thnaks Chris.
