My dad sent me this pic this morning. He traded for an Opal GT drag car within the last year. It had a nice running mild 355 in it. He decided he needed more hp. He built a 400 stroked to 426, was gonna be an epic build. He got it installed, Was running great. Took it to the track and it wouldn't spin past about 6k. He also kept destroying starters. He replaced all the ignition components, put a retard box on trying to get the starter to start it. He Decided to replace the flexplate as it had missing teeth. When he removed the flexplate. The TC wasn't seated in the hole in the crank and was bound up so when he bolted the tc to the flexplate, the flexplate, flexed.... a lot! They replaced it, cleaned up the hub of the TC and bolted it back together. Got it fired up and was setting the timing and such, they said it was running better, but still wouldn't go over 5k. Then it instantly seized, no warning, no noises, just 5k to nothing. This is what they found when they tore it apart.
