Default Modded 7.3 Pistons

We have in stock 2 variations of our modded 7.3 pistons:

Stock and .020 bore

They have an intake and exhaust valve relief cut in them and the fuel bowlis opened up for bigger nozzles.

I'll get a pic posted up soon.

PM me for pricing!!!

do you also do piston coating? How deep is the valve reliefs cut into the piston? Is there any way with the bowl work and the reliefs cut in does it alter the compression?

On EDIT: They look very good!!

Very nice! Any testing done on these yet? I'd be interested to see how the bowl configuration works with a stock injector.

We do offer them coated as well.

There is very little effect on stock compression.

The valve reliefs are cut .050 and can be customized to our customers specs.

The bowls are cut to optimize Jonathan's timing tables for specific injectors spray patterns. (I can't get into specifics) They too, can be customized to our customers specs.

They are in a few motors right now with great results. A stock injector is a great match for these pistons. Or should I say the pistons are a great match for the stock sticks. At this point all I can say is we have seen an increased potential of the stockers. After testing a few added benefits were reduced noise and heat with the loss of all the sharp edges of the stocker.

These are made in house and can be made from top to bottom to your specifications.

Is there anything that could be tweaked in the engine like a thinner head gasket to bring the compression back up? I would like to keep stock compression OR run a little more compression for quicker throttle response under the turbo.

Sending a PM for a price.

Compression is so close to stock you really won't need to worry about it.

Price list is being worked out right now....

I am sure we could do something about compression but I do not see the need. This past winter, two of the trucks that were running these pistons experienced NO white smoke on cold start up, even on 30 degree days or colder. Furthermore, the idle was smoother and quieter than most other 7.3L trucks, even though they were running larger injectors. With our programming, throttle response is not an issue.
