    Lunati cam #\'s

    I have a Lunati cam with the #'s 00017 and N4LD 112 on the end. Does any one know what these mean or where I can go to find the specs of this cam?Thanks-Russell

    It looks like this is the one you got
    00017 Good idle. Strong low to mid range torque and power. Power range 2000-5500.
    224* @.050 .460" lift

    '71 Blazer CST w/ a 400sbc, 4" lift, 36" Supper Swampers, and alot of rust

    I'd run a Comp Xtreme Energy 249-12-254-3, 2,800-7,000 RPM range. Thats the best cam I've found on the market. Other than custom ground cams.

    The cam came out of an 1/8 mile car and only had 2 passes on it and I had it in my blazer for a while but the power band does not come in quite soon enough. The guy from Jeg's said to go with a Comp extreme energy 254 w/447/454 lift and 256/268 adv dur. But I also found a comp 4x4 x-treme torque monster with 447/462 lift and 210/218 dur @.050". To me they both seem close to the same. Does anyone have any input towards either?thanks-Russell

    I would go w/ a Isky 201256. I have done some playing around on Engine Analyzer and that is the one that makes the flatest torque curve with nice low end. IMO both of those cams you listed have too much duration to make good low end torque. Also on a chevy you want to go w/ a cam that has the same lift/duration on the ex. and in. The chevy has a good ex port and does not need the extra duration (it just reduces low end power).
    Some of the guys have a copy of Engine Analyzer that I downloaded to a FTP sight...just do a search to find it and download it.
