They claimed to see it happen on the dyno. Sounds like a real possible issue.
thanks Greg, i knew this in my case im running a high pressure pump not high volume, as of now im loading up the city miles ans keeping eye on oil levels, ill be due for a change here very soon, i think when i reach a certian mileage and i got to 10/30 and i still see a high oil pressure i think ill swap the springs to the blue one if not mistaken. i guess i learn in due time what will beed to be done.

High volume sucks more power than low volume or high pressure and can over-oil the top starving the bottom. The LS has so much a better oil system than traditional small and big block engines it's tougher to do so. High pressure sucks less power than high volume but might also be unneeded. Call me what you want but in most of the builds on a site like this, a stock blueprinted/verified pump is the best.
Even though he builds mostly old school small blocks and an occasional big block, check out Joe Sherman. He has proven low pressure and low volume can make power as long as all the variables are under control to keep the motor safe....his builds routinely run small blocks about 8500 and big blocks past 7200 with common parts.
GG i really appreciate the time you take to explain, i been doing alot of reading but also listening to the builder, as of now hes really not concerned about the PSI on the oil, basically wanting to get through the break in stage then go from there, worse case would be lets swap the spring in the pump.
