If you just couldn't do oil mods, what's an alternative?

My dad has been running big blocks since the early 80's and I started in 2003. We have never done any oil mods. We do run a windage tray and a HV pump. We never built a stroker, just mostly mild stuff (under 11:1 comp). We generally shift the motors at 6,000 and don't turn them over 6,500 to try and help them live. We also run A body (Duster) He used to use a stock pan, but now we run the cheap 7 qt pans that come with a 3/8" pickup from ebay. We have to dent the passenger side some to clear the steering linkage when it turns the whole way. We've never broke an engine due to oiling issues.
