I bought a 454 from a guy that had twinn turbos and tore it apart to find it had no plugs in the front two 1/4 inch plug holes in the oil gallie. Can anyone tell me the reason why this would be. I would think it would have poor oil pressure. thanks

Someone made a mistake, and yes it would drop the oil pressure.

What is common is to drill a .040" hole in those two plugs to help lubricate and cool the timing chain.
