B3 Racing Engines Geometry Kit
Recently I added Eddy heads, Air-gap RPM intake, Hughes roller cam and roller lifters to my "LA" 360 engine. The Comp Cam roller rockers that was on the engine are 1.5 ratio and decided to reuse them. I bought these rockers from a member on here at least ten years ago.
After mocking up the valve train and checking the rocker sweep pattern on the valves with a sharpie I wasn't happy with the pattern. The pattern was towards the exhaust side and was wide on top of that. This is with the shafts installed straight to the heads... no shims.
Even though Hughes states that as long as the pattern is no less than .040 from the edge of the valve stem it will work. However it still bothered me that the pattern wasn't centered and wasn't narrow. I went ahead ran the engine and put some miles on her.
As like it was meant to happen I noticed a thread by Mike... at B3 Racing Engines. After that I went to his website and read his Engine Tech Series. After doing the reading I knew he was the one that I needed to talk with in order to straighten out my ordeal. Sent him a email and he gladly answered ALL my questions. I mean he went the extra mile with each and every question.
What I bought from Mike was custom Mopar geometry kit and PRW 1.6 roller rockers. It was like no time at all and everything was at my door step.
Now let me show you what proper geometry looks like!
The first picture is the "before" picture and is the exact rocker sweep. This is not a sharpie marked valve tip... this is the natural sweep on the tips. The second picture is with the geometry kit, and PRW rockers. I was absolutely amazed after removing the rocker arms and shaft to see what the pattern looked like! Daaaammmmmnnnnn!!!!
