    From what I have read, the corvette sump came with a heater option for cold weather, you just plugged it in and it warmed your oil for cold starts.
    Loads have removed the heater and connector, then then fitted an adaptor and there oil temp sensor in its place. Others have gone with your suggestion, and drilled out the oil filter cross over housing and fitted there oil pressure sender in it. So it seems like we are spoilt for choice, If I can find a spare oil crossover blanking plate, I will drill and tap it and fit my my oil temp sender in it, then leave the sump alone.
