The windage tray and factory studs cost more than the $140 for the entire engine. I've only found one place that sells new factory style windage tray studs (probably made in China) and the price is outrageous. I haven't been able to find used studs anywhere, including here. I'd buy the engine and get better pistons for it, as it probably needs to be bored anyways. If it's a factory roller block, even better.
