We don't have a dyno either, it's a 3rd party that also ports the heads we slap on ...
but our entire chain is by reputable shops that earn their livings doing this for many years and many cars, and it's all they do.
We have direct experience with over 200 engines from various builders, a very short list that we will continue to offer our customers. Any engine shop can build one good engine, I prefer track records and responsiveness to issues. If a shop is operating on razor thin operating capital to the point they can't build your engine without size able deposits exceeding 50% before your engine is complete, how could they possibly afford to take care of you if a problem creeps up? They cannot. They do not. We have first hand experience there.
We do have a chassis dyno but its not even setup yet.
