Well I'm looking at another Howards cam 260/268 duration and 555/574 lift with 108 separation. The lift seems a little low but the duration is where I think would work with my car. Gus Close to the 259/266 that mine is, but with less lift and 1* less C/L. open -------- close int.24.5 BTDC 54.5 ABDC ext.66 BTDC 20 ATDC These are the valve events of my cam. With this, my power band is 3200-7200. Torq comes in around 4300. My 2 step is usually set between 4600-5200.

Well I pulled the trigger and ordered Howard's flat cam 260/264 616/620 108 LS and I think I will like it. Also ordered the Direct Lube lifters and some Max ZPM break in lube. All in for $323.48 Still looking at springs,bee-hive maybe Gus
