Probably gonna build a touch more cylinder pressure than the original LT-1 cam...slightly less duration w/tighter LSA, but more lift...sound about right to everyone else?

should work fine..

I should've also added, it's geared more towards the bottom end than the LT1 cam...would be a good street cam I'd say.

The Edelbrock 7102 cam is similar 234-244 duration .488"-.510" lift. It doesn't make any real power under 3000-3500. It gives a nice exhaust note and doesn't mind lugging along in traffic. I would think that mine would need a 2000-2500 converter and 3.73 gears as a minimum to have any kind of decent performance in our el Camino.

I have this exact Crane cam in my 1970 Z28 and the car runs smooth and very strong! The factory LT1 cam was starting to show some wear so I chose this cam due to Crane's good reputation....which ever cam brand you chose, I'd recomend staying away from anything from Comp Cams...I know several of those that have failed and never made it past the break in period! Hope this helps.

COPO I had that cam in my Z and I was real happy with it,
She gets Real happy @ 3 grand and pulls real hard to 65-7000.
Dont even think about using pump gas though.

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.
