I decided that as my car was not running when I bought it that I was willing to rebuild it if the compression looked bad. This is what I came up with after putting oil in the plugholes and turned it over by hand. It turned very freely very easy. This car has been sitting for 16 years, as it did not pass smog for the PO. He said it ran great when last run. I pulled the Webbers that are in need of rebuild and you can see some carbon in the intake of the head a little so I am thinking vales.
The compression numbers where something like 120,60,80,60,40,70-I read that S cams give lower compression, but something is wrong as the numbers are all over the place. The one 120 may be OK This is what the engine has according to the PO. 2.5 L 20k Miles Aluminum case 2.2. Rods EMPI, 88 mm pistons and cylinders, Ported heads and manifolds 40 IDS Weber Carbs, CD ignition, 911S Distributor 67 911S Cams This would be my 3rd 911-engine build so I am not worried I just get help with the cam timing. I have bought a oil fed tensioner set I just do not know if I will need a full rebuild. Do you guys like this engine set up as far as the 2.5 and S cams?Ported, Perer Dawes of Dawes Motorsports built this engine in the late 70s. Bob Attached image(s)
