Reply to "77 Puma GTE Project."

I checked in on my Engine Builder, building me a 2276 out of the 2110 engine I dropped off. He is currently working on the heads. The Heads are older CB 044  Ultra Mag CNC ported heads. He found that some time in the past a nut or small bolt or screw found it's way into the no. 3 cylinder. At the time they a PO pulled the head and smoothed the rough edges but missed a slightly bent intake valve and a crushed top land on the piston causing the ring to be locked up. This is the real reason behind the low compression on no. 3 cylinder. My guy ordered a new SS valve from CB and is reworking the bowls of each head to match CC them and get the proper compression ratio without using cylinder shims. This guy has been building air cooled engines since the 70's and really knows what works.  He is super detail oriented. Some of the pics show the head and old piston along with the heads being opened up to fit the 94mm cylinders. I am getting excited to run this engine in the Puma long enough to break it in and get it fine tuned, it will then be listed for sale.
