Hi, We have a 1974 VW Bus that we are working to restore, and I have a question about the engine. We have pulled the original engine and have come to find that it has two cracked heads. We haven't determined whether the block is shot or not yet, but that's next. We are planning to rebuild (obviously) but we have run into a couple problems. One is that the engine in our VW is a 1.7L or a 1700cc engine. This engine was only used in the Transporter II for a VERY short time between the classic 1600cc air cooled engine and the change over to the 2 liter radiator cooled engine. So, finding parts is proving to be either difficult, expensive, or both. I have considered putting in a 1600cc engine, because it's cheaper, but there's 2 problems with this, 1) less power, and 2) I don't know if it will be compatible with the automatic transmission that we have already rebuilt. Any suggestions? Or even suggestions of where we can find information that would help to solve this problem? Thanks!!!!
