R1A 48 degree block NOT LIGHTENED and UGL Cam

What part # on Block?
Is it a 9.20 deck with 48 degree lifter angle?
9.20" 59 R3, there was a large production run of them machined with wrong cam tunnel. Easy to ID, just look @ #5 cam bearing bore, if it's the same size as the #1 bore, then it has a 48 degree cam tunnel in it.
Not to rain on your parade , but if this is what is then it takes a special cam and if LSM will make you one they cost about $800 just for the camshaft
