I think most call the original Torker a doorstop as well that being a single plane would rob lo rpm torque.I ran one in a stock 340 and it would blow the tires out easily at lo rpm and pull fine from idle up. Anybody can say anything on the internet and most mean well, but are often repeating things they have only heard. When you read a post that says "I tried this, and this is what happened" it may be more helpful.
