The not so Plain Bearing Revolution

2006 PRI Show Release:

Introducing Isky’s new EZ RollTM “needle-less” roller bearing option for Red ZoneTM roller lifters. Although they contain no needles, there is nothing plain about the cutting edge technology behind their proprietary material and design. Spintron® and field test proven over the past 2 years, EZ RollTM bearings carry far greater loads because of their vastly improved surface area to load distribution footprint, andnear-zero, ultra low frictional drag coefficient.

INTAKE:    A stock Super vic flows in its best runner about 298CFM, yet our heads can flow 327CFM.  The Super Vic, and was bolted to the heads and flowed on the bench with the heads on. Fully ported it now flows more than the heads can flow.

CAM: Custom cut Billet , press on Dist gear    Comp Billet Solid Roller Profiles were : RX 4304/NC 4145 259/262@.050 .430/420 .688/.672"lobe lift 112LSA  

The cam comes from the NASCAR and ARCA line of cams. Specific to high continoius rev application past 9,000. As mentioned for the street I currently limit revs to 7,000, but the cam and springs are well suited to much higher RPM's. Below is a cut from the actual pages of comp where the lobe profile for this cam was taken. The cam is not an off the shelf grind. It was custom cut, and engineered for this application for cubes, and airflow of the AFR heads. The colaberation of many were involved in choosing the profile for my cam. From engine cubes, airflow, vehicle weight, gearing and my personal driving style, after many hours of calculations, we managed to fit the best possible cam to the Nova.

If you notice our intake grind RX 4304,  is not listed on the page below, it truly is a custom grind, a one of to suit the Nova. If I told you the names of the people who colaberated on the cam pick, I would need to blind you while reading, its a secret, but I am pretty stoked about who all was involved.  The cam came within a few HP and TQ of what was projected, needless to say it is  a street friendly cam that  DELIVERS, and delivers reliably. 

 Joe Sherman would have stuck a 288 @.050, or bigger, as he is a big stick lover. We would have made well over 725HP with that duration with a bit tighter squeeze, but then lost all street friendly manners in the process. We built street friendly, not just a balls out bragging HP numbers motor. 

 

 Jesel Pro series shaft  rockers are 1.6 IN and 1.6 EX made specifically for the AFR 227 heads. The heads have 60/40 valve spacing in that the intake is moved from a stock location. The valves are intake  2.10", exhaust is 1.6"

 I purchased the lash adjuster tool and it was used to secure, and TQ these, not just done by feel, or hand tight. Lash distance was as per Comp. The adjuster tool has a built in TQ wench, and adjusts the TQ of the nut to Jesel spec.

We ( Terry Kershaw due to my physical limitations) have adjusted  valve lash shortly after dyno break-in, and every 2,000 miles since, and it has NOT changed a single bit.
