Here's the equation to work it out.
 

Yeah that works out right on a 0.030" over-bore.
 
Would need custom clevo pistons with Chev pins, or bushed to suit. The rods are machined on one side of the big end to get the right width on the journal. The crankpins are pretty thin once machined, I think the fillet radius size is critical, otherwise cracking is a problem. If the crank's a 4MA or 4MA-B, much better.
 
No further experience than that I'm afraid. Should be a torque monster.

gerg is all over it.  Always ran a complete thermostat - even in the burnout ute.
 
another thing I have found is that with no thermostat the water just blasts through the radiator back into the engine.  It doesn't have anytime to cool in the radiator because the water is just continually cycling.
 
With the thermostat, the water is held in the block so it can heat and this gives the water in the radiator more time to be exposed to cooling air.

Absolutely none, but there are plenty of reasons why you should:
 
* The hotter the engine, the more efficient it is (to a point, then knocking and seizing are issues). This is because heat loss to the cylinder when cold is greater than when hot. Heat is what causes expansion thus the more expansion (bang) the more torque.
 
* A hot engine atomises the fuel better, requiring less enrichment for the same power. Conversely, a cold engine needs to run rich because only a percentage of the fuel gets burnt properly. The rest goes out the exhaust.
 
* A cold engine has fuel condensing on the cylinder walls, diluting with the film of oil on them and ends up in the sump. An engine that runs cold a lot will have oil that smells like petrol. The oil thins out over time and loses its film strength.
 
* The Water pump needs a restriction to pump against (ie thermostat). Not having one causes a low pressure area in the middle of the impeller and a cavitation bubble forms, reducing the pump's efficiency and causing damage to the blades over time.
 
* A cold engine has poor emissions performance, and some functions may be disabled (ie can purge, egr). Not that anyone cares, but needs mention.
 
* A cold engine has looser clearances, so will use more oil.
 
* Cold oil has a high viscosity, and has poor splash lube capability (ie bores and camshaft)
 
So in summary, yes you should run a thermostat.

Only if said thermostat is jamed shut.
Even then I would recommend cutting the guts out & refitting the plate to offer some restriction of flow.

Ultima = Chinese shit!

I liked how the XD came out with that choice stu, from factory it has 2 mounting positions to suit.
BW and C4.

Yes. You might need to move it back to the second by hole on the chassis.

That's just silly. Anular booster wheel nuts will be perfectly ok for this application!

The double over head junker pumper needs to set at .000002 lash at 27.5 degrees before top dead center, with the engine cold.

Anal booster? Lol.

You need a new set of fuel injected wheel nuts

My engines making a noise what's wrong with it?

So much easier to diagnose in person than over the net!

The Reaper has been a 6 year project so far, but finally finishing him off.

Yeah I get to that stage all the time, Ive just learnt now to stop and come back when I feel like doing it, other wise Im doing it again.

Thanks mate, I appreciate your input, could have been a few months earlier though hehehehe, but the elogated holes turned out alright, and the engine fits in nicely, there is room for all hoses at the back and the gearbox fits and there is plenty of manoeuvre room with the tail shaft, so Im a happy man.

Your idea does have merit, though. Next time......
