Re: NOS L88 Cam??
Part #3925535 casting number #3925536. L-88 camshaft for 1967. Lift .562/.584 duration 354/360. The date code looks like September 23, 1969. The other one looks like May 16, 1969. I know that all the early cams I have had has the Circle M on them. Later ones from the mid 70's to 90's don't have that mark. Is there "RSCL", a "65", and a "CWC" casting marks?
