cylinder head question?/AGAIN

Thanks john, what were the dyno machines? What ones are OK and best these days?

The dyno is superflow , remember a dyno is just a tool , use it for what it is , a load testing and tuning tool .

The real dyno is the dragstrip , ET and MPH and the cars weight tell the REAL story .

There's a big name ship in the mid west witha very HAPPY dyno , numbers are 100 plus inflated , engines that dynoed at 900 hp got the cars they were in only into the 10's .
