How much power will a 4G64 block hold

[Clipso 1]

Im trying to figure out how much power a stock form 4G64 BLOCK will hold, not the parts inside the block, but the block itself. I am going to be buying all the other parts later but for now I need to see if I need a custom built block or not.
Thanks,
Jeremy

I bet the block would handle atleast 1500 flywheel hoorsepower.

Where do you plan on getting one of those?

There are all kinds of people that will build stuff if the money is right.

Since the cylinder walls are thinner than a 4g63 block you'll have to consider when or if you'll have problems with the cylinder walls splitting. I'm guessing the limit of a "stock" 4g64 block might be in the mid 800hp range.

In a race application you could fill the blocks coolant passages and make it more reliable.
