Has anyone used Racetec pistons? Any issues or concerns?

Not very good at custom Pistons

The ones I received with my Bloomer Performance Engineering stroker kit for the small block were perfect.

I have two sets but neither has been run. I got them from my machine shop that really likes them. He used them for many years in circle track motors for one of the top teams in our area. He never had any issues. They mic out good

There is some Autotech brand pistons in the 416 my Dad and I built. I think they are the lower line from them but they were a very nice looking piston.

Racetec and Autotec are both companies started by a former engineer from JE. They are quality parts.

I have them in my 468 small block, no problems, my machines like them.

Please elaborate.

Thanks for the responses. It sounds like almost everyone is happy with them.

I have one friend that has gotten Pistons twice with great results Street strip application from them.. I have two other friends that have had then make custom large Dome Pistons and even when they were provided a head they couldn't get it right... I think they are fine for a common run of the mill pistons.. if you do a Google search on them you will find mixed reviews.. some people even question the material type of there blanks...
