Building lsx 427 from l92 block

I would not run over 10lbs honestly...but 10lbs will be alot different on stock heads vs 10lbs on say a trick flow head (assuming we are strictly comparing ls3 heads). If a competent/reliable machine shop sets it up for boost then I would run it like any other boost setup. And it will be different with different cam profiles as well to a point.
The stock pin on an ls piston (besides ls9) is .944-.945. Nearly every aftermarket pin set for any stroker build is a .927. Some of that is due to rod and pin availability and ease of availability of parts and manufacturing. And some of it is due to pin placement and ring pack placement. The CH on the can be the same on 2 pistons but if one has a .945 pin and one has a .927 pin, the .927 pin piston can have more available material for piston strength and more room for a ring pack without bridging the pin hole and having to use support rails. That is extremely oversimplifying it of course but that is a short explanation.
There are so many builds out there that ARENT on tech or cf. Not everything gets put on the internet either.
