Clevite cam bearings SH290S v. SH287S
Question for you engine building gurus.
Getting ready to built the LT-1 engine for the 70 Corvette. Seeing two different part numbers for Clevite cam bearings. SH290S SH287S. Did an internest search but found nothing. Can anyone tell me the difference?

Far from an engine guru but could offer my 002 cents .1955 - 1963 had the cam groove offset to the back of the block , the sh290s rear cam bearing has 2 oil holes drilled.
