Building a 10,000 RPM Jeep 4.0 - Best Heads and Intake

Rick Mudge was the engineer in charge of airflow development for AMC/JEEP/ CHRYSLER engineering from 1976 to 2001 and developed the 4.0L jeep cylinder heads intake and exhaust manifolds through those years.


Rick developed a 4.0L JEEP engine for drag racing in the NHRA Competition Eliminator class. His engine set the ¼ mile national record in 1996 at an 8.60ET/ with the best speed of 150.90 MPH spinning 9000 RPM through the traps. This engine was built with a combination of stock and heavily modified production and racing parts. Through this multi-part series, we’ll learn who Rick is, his work, and his formula for building a 10,000 RPM 4-liter Jeep.


I’ll warn you that the audio quality is only as good as Rick’s flip phone would allow, this wasn’t recorded in a studio, and I’ve done the best I could to clean up and mask the poor quality recording.


In this episode, Rick tells us which head casting is the best to use and how that head casting was almost lost due to some corporate shenanigans and some of the shortcomings of the stock intake manifolds. Don't worry he also covers how to modify the stock manifold for increased power.
