A to Z Posted February 26 Author Share Posted February 26 (edited) Time for an update. The short block is still at the machinists,:( and I got the chance to buy an E31 head that is ported, with L28 intake valves, Electramotive L4 cam, springs all the good stuff, 500-1000 miles on it. Well, the head arrived and I took some time today to clean it all up. Using a brass wire wheel attachment in the drill I cleaned the whole thing, and then CC'd a chamber. The head was shaved, and the machinist left .060 stamped in the corner....it's a lot huh? It cc'd at 37.5cc and stock would be 42.4, so 5 cc less. I used some brake cleaner and a toothbrush and I got it all clean and ready to go. In the pics to follow you can see how clean the valley around the valves, look how clean I got it. Here are the cam specs. I found these on here, from May 26, 2006, member: Phred Electramotive L4-02; Y84N; 7151. Ground by Ron Iskanderian at Isky cams a LONG time ago.
