greetings, im back for more. i came across a good used free camshaft from a buddie of mine.its a hydraulic cam and the specs are the same as the edelbrock2107 or 2101. and i all need is lifters and the rest of the installation stuff to get it going. now, do i just lube up the cam and lifters and go..? or do i still have to break it in like its all new and rev it up too 2000rpm for 20 min and then change the oil...? used cam, new lifters, that would be a first for me,, and i dont want to mess anything up. if i left out any info, let me know,, thanks.
