    Hello gearheads! After checking retro posts I haven't found anything on this stick, and wondering if anyone had used this one in the past. I'm really liking the numbers on this one. It's the Crane "Saturday Night Special" 284/290 grind.
    228°-234° @.050 and .480/.490 lift on a 1.5 ratio. 106° lobe separation. Grind # 110591. Plan on using these with anti pump up lifters. Has anyone used it before? I'm using ported "601" heads, chambers massaged, (no sharp edges) stock intake valve and 1.60 exhaust valve. 10.3:1 compression. It's going to be a fun motor to beat on not driven daily.

    Sure no expert here, but that's a pretty radical cam. Can really perform but a bear to get tuned just right. Those heads work with a near 1/2" lift? I'd back off some on the cam but that's just me. Somebody with a lot more experience will probably check in on this.

    Cam choice is dependent on many factors, car weight, intended usage, compression, heads, intake and exhaust run, rear gears, trans (auto or manual) just to name a few. Critical is an honest usage acessment. I will tell you it is far better to under cam than over cam. Do not know of anyone who has run the "midnight special" but it may not pull enough vacuum to operate vacuum assist power brakes given the 106 LSA. Though a narrow LSA may produce more peak power it does so by sacrificing a wider torque curve which gets you down the road. That cam ground on a 110 or 112 LSA will be more flexible to drive. Currently I have a Lunati Voodoo 10120703 hydraulic flat tappet. Very pleased, pulls hard to 6800rpm with the heads, intake, carb and exhaust I have and idles at 750 rpm with 14" of vacuum. Your best bet is to fill out a cam recommendation card with several cam companies to see what you need to meet your expectations. Fyi, Lunati said the 10120703 or 10120704 would work, for me. I selected the slightly milder cam, the 10120703 and haven't second guessed my decision with 8k miles on it. Hoping Lunati can supply me with a roller version similar in specs to the FT 10120703 to put in my new 355.

    That's about where I want to be. That's a nice cam.

    I have run the 110691 (one size larger than the 110591) in an old 11-1 355 with a 4.10 and a 10 inch TCI 241000 converter. Great camshaft.
    I have also run the 274 H06 in a flat top 350 with a factory stall. Ran really strong.

    That 110591 would really be a nice cam for you. IMO.

    Thanks! It is a fairly radical grind. The motor is going in a light vehicle. (2650) with 4.30 gears. 26" tire. Turbo 350 with 4k stall and shift kit My course of action is to use variable duration lifters to knock it back a little closer to the Crane 274h06 during normal street load. When I gouge it, it's game on for full cam. It's not an application I'm taking into the city. It's gonna be a fun toy to blow off steam with in rural area. 50 mph roads. Not much stop and go. Maybe. "Big maybe" some test and tune nights. It's gonna get beat like a red headed stepchild.

    I'm running a Saturday Night Special 110922 in a 388. I have a lot more cylinder head than you do but it definitely pulls hard with a stall converter and steep gears. I also still have enough vacuum to run my power brakes. At the end of the day I wish I would've spent the extra money and gone roller though. I can't help but think I'm leaving some power and drivability on the table.

    You will go roller after losing a 2nd FT cam as I did.

    I'm leaning that way. I like the numbers you're running COPO. Does it idle nice for those duration numbers? Just curious. Bettajdbka~2.jpg
