I put the cam/lifters/chain/both sprockets in the 1st week in June. I broke the cam in using JoeGibbs BR oil for 40 min per Cranes instructions. Dumped the oil/filter and refilled with BR oil for 100 mi still with my old 43,000 mi springs. I'm now in the process of changing my valve springs and valve seals then I'm going to put 400 mi on the car before dumping the BR oil and going to JoeGibbs Hot Rod oil. So far the cam wasn't working as good as I thought but I still need to set my total timing to 36*, change my coil to a MSD Blaster 2 and install the Crane XR-i Points To Electronic Ignition instead of points and 1.52 roller tip rocker arms and of course the valve springs. A few years ago my Pertronix died that's why I went to points (to use them up) then I saw the Crane with a rev limiter.

Car is a 4 speed w 4.10 rear gears. But during my 1985 rebuild, I went to 9.0:1 Vanolia 40 os pistons due to the low actane gas on the street. Before the LT-1 cam wore out 3 lobes (probably from dry starts using Mobil-1) it worked good but I wanted a cam that would start to work sooner than the LT-1 cam. That's why I went with the lower duration. To try it out.

My next rebuild will be full roller.

I had the Crane cams XR-i electronic ignition in my Nova and loved it. The cam specs on the 427 I had in it said the cam was good to 6000 rpm. I set the rev limiter to 6250. I am an rpm junkie so that helped me keep them down.
