ERA Chas, my motor is number 27. When we got it it looked very solid and well cast. After we started to go throught the machining process we discoverd some problems. Number one was when they drilled the
oil galleys the didn't hot tank it afterwards as to get all the metal shavings out. It didn't even look like they blew it out with air in some spots. What happened was all the shavings rusted together inside the galleys, a real pain in the ass to dig all that stuff out. Number two when they were drilling the
oil passages for the heads they never conected. You had the hole from the head deck going down to the
oil galley and you had the hole from the oil galley going toward the head but they never met. Minor problems but the block was by no means ready to go togher as advertised. Now that it is in the car and running fine I see a big diffrence in the water temp. It runs about 15 to 20 C colder than my center oiler did. This very well could be that the bore is standerd as my center oiler was 30 over. Hope this answers some questions if you have more I will respond. So far I am happy. We will see when I have a few thousand miles on it though.
