Mec, there is a few things that I am doing but the big ones are replacing the cylinder heads with JHM rebuild cylinder heads, doing a timing chain service, installing the new version 2 mid-length headers, and reinstalling the stock sixth gear set in the transmission. Euro is right that I have leaking valve stem seals. Then the engine has 104K miles and it has never had a timing chain service plus that stuff has to be opened up to replace the heads anyways. I got the version 2 mid-length headers too since I was taking everything else out. The old version 1 longtube headers are already sold so that helps. Finally I have run into a few instances where I need the stock sixth gear set in the transmission like driving through the mountains and on certain road courses like VIR. I hit like 150 mph in fifth gear while going up the back straightaway long before I crested the hill at VIR and then shifted into sixth gear which doesn’t go much faster. With the stock sixth gear set I bet that I can hit 7K rpms in sixth gear which puts me around 175 mph.
Euro, there is always a plan when I take stuff apart. I can’t afford to just take stuff apart for the fun of it when I have so many people that want me to work on their cars locally.
A lift is such a nice investment! I wish mine was inside so that I could work on stuff year round and regardless of the weather. One day I will add on to this house and make a spot for two lifts but that is a few years and hundred thousands of dollars away.
