Ok, going to be lots of pictures in this one. First off was mocking up the valve train for one cylinder using light weight checking springs and adjustable push rods to check both for piston to valve clearance using clay stuck to the top of the piston in the valve reliefs, and to also adjust the push rod length until we get the correct valve stem to rocker contact. After the valve is pushed into the clay, we section the clay and measure the thickness. This tells us the distance between the valve and the piston at their closest point. Now that we have determined the correct length the push rod needs to be, we can order the push rods. Next we installed the oil pump and oil pump pick up. We then remove the light weight check springs and install the correct valve springs. The next job was supposed to be simple, knock the pin out of the distributor gear and using a gear puller, pull the gear off the distributor shaft. The pin came out easy enough but we couldn't budge the gear with the puller. You know when you have to get the cutting torch out that things are getting seroius. We heated up the gear to get it to expand a little but the puller still wouldn't budge it. We moved to the hydraulic press while the gear was still warm and pushed it right off - yahoo!! The reason why we had to remove the gear is that a stock gear is made of iron. We have a steel billet camshaft in this engine which would eat this iron gear alive. We needed to install a steel gear in it's place. Thanks to Kevin, Dave, and Charles for coming out and helping.
