Yes a good engine builder will take car of his customers.
I recently received a 565 supercharged engine from a builder and have not even asked him for any help on it and tried to send him some business in the way of two complete short blocks, He blew me off, Now I'm not sure if I want anything to do with him. I will give my money to someone who is not so arrogant and Just can't deal with it.
So far there have been 2 major builders that have gone this way with me.
So what If I am not ordering a $30,000 pro motor, It is still business.
