TRW piston id

Thanks!!! I’m just fine with it being a stock build. Just going back into my w200 for use as a truck again instead of a paper weight. It has been decked, I’m pretty sure of it. pistons are about .04 down the hole at TDC.

What’s the point of the notches on the side there
I ALMOST included that it would be a FANTASTIC truck engine AS IS as far as compression. With the correct camshaft, and matching bolt ons to match the compression, it can be a torque powerhouse. In fact, that's how I'd build it regardless of what it was going in. I think people put too much emphasis on compression because of all the magazines and forums. It will run fine.
