Re: flow numbers ?
 

It always seems to tickle me when anyone asks for a average number for head flow or, what should an average 255hp 350 S/S engine make on the dyno. You would think people have asked for nude photos of your mom , or pics of little henry lol. For sure if I had found an additional 20hp I sure as hell would not tell that I have found it or what I changed to get it! As Adger said flow numbers don't tell the while story, or does a wicked peak hp number make a car quick when when the engine is a turd in the midrange. It would be nice to get some average numbers to know if you are in the ball park. Don Jackson

Thanks for all the good info guys

Re: flow numbers ?
 

I agree. Mid lift numbers are very important since the lift curve sees them on both sides (opening and closing) and more time is spent there than at peak.
