The Predator Head was developed in conjunction with Steve Gill to create the world’s best cylinder head for the 4.800 centerline Chrysler engine. Available in both Hemi & Wedge head bolt patterns, the Predator is a symmetrically designed head to better equalize heat and make all runners and chambers exactly the same. Air flow numbers above 530cfm with a 2.450 intake valve and 460cc CNC porting are easily obtained. Intake air enters the combustion chamber as far away from the exhaust valve as possible allowing for better cylinder fill and consequently more power. 1400 horsepower with a 655 cid top dragster engine is the standard at Indy.
