    This is all great info. Has anyone taken the 'super' cat cam and advanced it back to straight up to bring all that HP down a little?

    Wow Bill, I HAVE that cam! :beer
    I bought it years ago in a package deal, and put it on a shelf. It's real close to my Isky 310...my Isky has a bit more intake duration, and closer lobe centers.
    I always wanted to try it, just need to get the lifters.
    Is this cam in your Blue 'Cat??

    We will be using a cam specifically made for our application many years ago & were not able to use it because of V/P clearance issues. Now that has been overcome. Guess we'll find out how or if it works. Some of the specs. 274*/274*@.050". .400" lobe lift. RPM range????? With the "Rockers" we were able to go to 7100 & did not find the drop-off point with the older cam. Using stock "Rockers" actual lift at the valve .570". With the "Rockers" actual lift at the valve .792". Will find out at Dyno time if it was worth the time, effort & $$$$$$. Hopefully 10's here we come. If calcs are correct compression will be in the 14.5-1 area. If nothing else with this compression the exhaust should have that "Crackle" to it like the ole gassers of the past, maybe?

    I have been running this Engle cam for about 12 years or so now,

    (info taken from mid 1960s Engle Cam catalog)
    Engle solid tappet part #1901, cam grind #322, type 'Super 3/4'

    Lift at valves .460"(1.5:1 ratio rockers)
    .480"(1.6:1 ratio rockers)
    ( I am not sure how they figured that out, the numbers
    don't work out quite right- I never measured lift at cam
    before installation-but should be right around .300")
    Duration 274*
    Intake timing 30-68
    Exhaust timing 68-30
    Valve lash (hot) .018"

    I have two Isky roller cams (only one set of roller lifters so far but looking for more) which I am planning on using soon.

    1) Isky '505C' roller cam

    Lift at valves .505" (adv gross using 1.6:1 ratio rockers)
    Adv duration 320*
    Duration at .050" 274*
    Lobe seperatin 110*
    Intake timing 50-90
    Exhaust timing 90-50
    Valve lash hot .028"

    2) Isky 550 Super Legerra, grind #RR-550, type 'Ultra Super Track'

    Lift at valves .576" ( using 1.6:1 ratio rockers)
    Lift at cam .360"
    Duration 330*
    Lobe seperation 108*(this is not good)
    Intake timing 57-93
    Exhaust timing 93-57
    Overlap 114*
    Valve lash .018" hot
    (above timing given at .028" lifter rise)

    (following timing given at .050" lifter rise)

    Duration 282
    Intake timing 33-69
    Exhaust timing 69-33


    I also have a few 'hot cams' for 322" but no specs for them. I have a factory Export cam, an Export cam reground by Ed Winfield, a Weber solid, and a Harmon Collins Roller. I need to do more research and see what I can come up with for specs on them.

    The specs for the 322" factory 'Export' cam are:

    Lift at valves .420"-(I assume using 1.5:1 as the ratio as this was for the earlier motors)
    Duration 297*
    Intake timing 34-83
    Exhaust timing 76-41
    Overlap 75*

    If any one has any roller lifters they are looking so sell ( or trade?) please let me know. I have three roller cams and on ly one set of lifters for them. I may look in to having Chevy roller lifters modified for use-mainly just having cross links made up.

    Here's a question for all the smart people. I have a pretty nasty cam in my 65 Wildcat, but used Rhodes lifters to help the vacuum and idle quality. I have always been happy with the performance of it, but what are your thoughts of using a bleed down lifters? Obviously this question applies to hydraulic cams only. I would guess that a solid lifter cam would be a bit unrulely on the street.

    Sig Erson 140 H
    part Number 625821
    IO 41, IC 81
    EO81, EC 41
    .480 Lift at 1.6 rocker ratio
    302 Duration (I believe this was at .006 checking clearance)
    (going from memory from 1972 :>)
    I believe the lobe center is 110
    Valve Clearance is .080 Intake, .085 Exhaust
    @ 2 degrees advance (at 4 degrees advance, intake valve clearance was only .020)

    CAMSHAFT DESCRIPTIONS

    Performance street and strip cam, gives 25+ HP increase. TA 1440 Stage 1 springs required. Moderate idle. 2000+ stall
    converter recommended.
    Recommended for all around street performance, an upgrade over the dual quad Riviera cam gives 20 HP increase in
    most combinations. TA 1440 Stage 1 springs recommended. Stock converter and gears ok. Good idle.
    Similar to stock with some extra lift resulting in the same driveability as original. Works well with low compression
    engines and smaller displacements. TA 1440 Stage 1 springs recommended. Stock converter and gears ok. Good idle.
    Great street/strip cam, makes lots of power without compromising drivability. 112 degree lobe center allows the use of
    more boost before experiencing detonation. Smooth idle.
    Hot street/race cam, gives 40+ HP increase. TA 1440 Stage 1 springs required. Rough idle. 2500+ stall converter and
    gears recommended. A great cam to really bring out the power of the Nailhead engine.
    Hot street/race cam, gives 30+ HP increase. TA 1440 Stage 1 springs required. Fair idle. 2500+ stall converter and
    gears recommended.
    Smooth Idle


    - just like stock, Good Idle - mild lump, but doesnt impair driveability, Moderate Idle - nice performance sound, Fair Idle -
    heavy lump,

    Rough Idle - very lumpy race type idle

    As far as the forged pistons: Diamond, Egge and I think Ross... may be more but may be of questionable quality.

    Where did you buy the roller cam? TA?

    I'm sure you can get the lifters from TA, but you'll have to call becuase last time I checked they weren't on the website.
