Big Block seems to slow

Here's another thought to why it's not running correctly. Does it have the correct spark plugs in it? Recently a guy running a BB Mopar at the track was having a poor performing car. He ended up having the wrong reach spark plugs in it. He changed to the Autolite 85 plugs I recommended and the car picked up 3/10 of a second in the 1/8 mile. Lots of little simple things can get in the way of good performance.
