Would these gm crate motors be as reliable as a Texas speed or mast motorsports crate engine?

They'll have a better warranty so long as the only thing you ever crack open is the oil cap.

Are there any internal differences in these crate motors and the Ls3 motors in the camaro or corvette?

I was wondering if they used the upgraded cnc heads but I guess not

So who has a 525 and how is the drivability? Auto or Manual?

In the process of installing the 525 now. I bought it specifically because it is a gm crate motor, and should be daily driver dead reliable (start up ice cold in the dead northern winter and go). This is a summer, no rain, only car, but I still wanted the reliability.

I had the T56 rebuilt by Tick (stage II)
