Moot Point, it won't get custom headers, neither me nor the owner is comfortable pushing 900+ through a factory block.
It's not a race motor, it's a streeter, the extra power wouldn't be noticed but may kill the block.

Down the track if/when we get a local strip up & running again we may go to an aftermarket block & turn it up for racing, but until then we'll leave it be.

Don't worry about the block, it will handle the power.............at those low rpm's last all day. Owners going to S**T himself on the street with this build.

What car is it going in?

Nice, im doing a 557 with ported p51s. Very similar combo, just a little more comp and a little more cam. Hoping to see 850 from it.
