A couple of local shops who do a lot of engines call me if they have a customer who wants a Mopar stroker engine built. These guys are so busy building engines all day long that they don't have time to research what is available. One guy just always used Indy heads since that was all he knew about until I showed him a set of Trick Flows. Once he saw the Trick Flow heads he switched.

If the customer doesn't know much about Mopar engines and he goes to a shop that doesn't know much about Mopar engines then the end result might be really generic. Even if the machine work is perfect, the engine might not perform great, or it might cost more than it needs to.

Does the shop knows that Molnar makes Mopar cranks or do they only know about 440Source? Do they know that Mahle has Mopar stroker pistons with a metric ring pack or do they just order the Icon pistons? Good engine builders tend to be in high demand which means they are super busy. Probably too busy to spend several hours researching all the options for an engine that they don't see very often.
