I wanted to share the engine build on my 1997 GTS. Just thought others might be interested. The engine had been consuming a lot of oil. That with a frustrating vibration at around 1250 RPM which became noticeable after installing the woodhouse poly mounts finally convinced me to have the engine pulled and sent to Arrow Racing Engines. I did explore buying a used engine / bottom end to replace mine. I have not had particularly great success in purchasing used so even after finding a couple of possible candidates I opted for having the engine torn down and checked out. I couldn't bring myself to take the risk of buying a problem instead of a solution. As it turned out the engine bottom end had a "few" problems: a couple of rod bearings down to the copper the crank was damaged and beyond repair the cylinder walls were heavily glazed and the oil pump/front cover was shot at least the engine is numbers matching to the car So while the bottom end is getting built back to stock performance a set of GEN IV heads will be going on the engine as well. The bottom end will be primarily stock. A slight overbore to deal with the heavy cylinder wall glazing and a stock crank. There will also be updated main bearings which are the biggest thing to help out with the oiling of the rod bearings. Naturally, all of this was very frustrating to discover and is really frustrating for my wife. She really enjoys going cruising in the Viper and the down time on this is not fun for either of us.
