If you’re tired of looking over your shoulder to see your competition take action and call us today. Whether you’re after a NHRA .90 MPH Monster or a 4.30 player (3,500 DA @ 1,800+ lbs.) for Big Money Bracket Racing these Frankenstein modified DN-9 heads are the answer. Watch the video from SDPC Raceshop and how they used these DN-9’s with a ported Edelbrock manifold to make over 1,300 h.p. with an Advanced Product Design carburetor.
If you asked Big Money Bracket Race Winner Jason Enfinger about this combination he’d say “We know that the less time spent on the race track the less time there is for variation in conditions to affect the car. It seems like everywhere I go only guys with fast Roots or ProCharger supercharged combinations dial quicker than me. This combo is perfect for anyone wanting to be as consistent as possible in a dragster without all the fuss and maintenance of a blower. With this much power it gives me the ultimate advantage when driving the stripe. Paired with a new FTI billet bolt together converter all I have to do is let go on time!”
