Alistair Bell writes that he has "But lo, another mystery... one of the pushrods has been "grooved" about 1 1/2" from one end. It is as if it was done on a lathe, 1/4" long, 1/4" deep. I only noticed it after I had all of the pushrods from one side in a tub so I don't know wether it was the head or case end." I had this on my 69 with the destroyed block- my best guess is that my pushrod rubbed on the outside of the follower. Alistair, if you slip a follower into one of the bores, you'll quickly see whether the groove matches the case end of the pushrod tube or the head end of the pushrod tube- you might want to stick a finger or shine a flashlight into each follower bore and make sure they're intact. You might just have had a bit of something sticking out from the edge of the pushrod tube too... "Parkerized" is a proprietary process for hardening steel- could that be the word you meant? Cheers! Bill
