I started to strip my 69 2.0t engine.. I was told that it has E cams and pistons .I will CC the piston domes tomorrow. Any one know what the different cc for the T-E-S pistons are?

Cam markings are 901 105 109 01 and 901 105 11 01. Production dates 23966 and 16766. From what I can find these are out of an early 2.0 litre. On the front of the cam both have 05 stamped. Are these solex cams? Before taking apart I checked the overlap left 2.6 and right 2.8. I found info on the forum that these should be 4.2-4.6?

thanks Jake
