OK on my 70 Nova 350 stocker build, I have the new motor in, fired it up with the Gibbs break in oil for 25-30 minutes at 2000 rpms using the low tension valve springs. Changed the filter and replaced the lost break in oil. Any thoughts out there about letting the break in oil stay in it and running it some with the new springs or does the break in oil need to come out now that the initial break in time is done ??? Any opinions on where to go from here ??? Is there a rush to get the break in oil out ???
