That is plenty of pressure at idle for a Chevy SB . Got a 360 (.060 over 350) in my '65 GMC that was set up with round track clearance (bought it unassembled). Never has run over 38lb hot and around 10-15 hot at idle. Now with over 100,000 miles still runs 38 and 10-15 and still does not use any oil between changes. After all when the chevy SB first came out 35lb was the stock figure.This is my go-fer with the above engine:
