    Anyone running this cam in there 350 engine?
    I'm re building my 72 350 for a daily driver purpose.
    Block is .030 over, heads are mildly ported with stainless valves. 10.1 comp.
    Had a Isky 262 prior build and ran well. Any feed back would be appreciated.

    I ran this Crane Hi-Intensity 216/228 abt 25 years ago. Good street manners, great vacuum,
    Nothing radical.

    Your Funny Larry. =)
    Spoke with Comp today, he recommended the 212/212 High Energy cam
    for my 10.1 Buick 350. Cam cores are not available these days and Lifters tough times.
    Very close to that Crane cam Mart posted. =)

    I ran the 268 in 1983 does that tell anything about this cam? not really a Buick cam no spread on the intake or the duration which is what the Buick engine needs.
    The cam needs a 2000 convertor to work and it did not get going till 2500 rpm and was good to 5500 rpm. A better equivalent cam would be the TA212 cam Or the Lunati Pop mechanics cam that I currently use I got from the GS club I have ran this one for over 20 years now.

    I bought a new cam from Schneider I got this in 2 months last year going solid lifter this time.

    Is that really the best cam Comp can offer you? They should know better than that this just proves they do not want to make a cam that will work in a BUICK engine they want to give you the off the shelf Chevy cam for a Buick.

    This stuff really galls my ars as their are better options for a 350 Buick engine Comp is full of crap on this selection

    Mart's cam is really not the same as the 268 he has a spread on the intakes and duration.

    I wish some one would write a book on this 350 as there is some crap info on these 350's and not all 455 things apply to this engine.
    It Is a different animal even though it is the 455 brother.

    If you have not had your heads flow tested after your porting work then you have no idea of what your Exh to Intake ratio is now.
    Let me also say this, if you do not have headers on the car then you for sure need a duel pattern and not a single pattern Cam like your asking about.

    comp xtreme energy 212-218@.050. 477-485 lift. more important is your 10.1 compression with iron heads with the smaller camshafts. i would try to get it down closer to 9.5. a conservative distributor advance wouldn't hurt either.

    Yes, with a static compression of 10.1:1, that cam (268/268/110) will produce a DCR of 8.35. That's very close to Race Gas required.

    Hey Great info guy's Thank you! I think the TA212 is the answer I am looking for.
    Larry , my static compression is 10.1 what would my DCR be with the TA212 cam?
    Pump gas of 91 octane is what's here in California.
    Yup, running Headers and Stage 1 350 Intake.

    the 413 cam may work good for you since you have 10.1 comp if they do it 0n a 113 lsa it will keep your vac up unless you have power brakes but it should provide 13 inches of vac at idle. 413 might be a bit much. A couple people have used the cams a step above the 212 and the didn't seem to have real good luck, those are in between the 413 and 212.
    I like the duation and lift on the 212 could probably go closer to .500 lift too bad that cam isn't up that much
    I think 225-235Duration at.050 and a 500-510 lift with 112 lsa would work good at your comp
    I still put in 5 gal race gas in mine I just do it for safety since my comp is at 10.6 iron heads

    honestly, there hasn't been enough testing with 350 cams to know which does work better with around 9.5-10.6 compressions. But I am going to try a 3rd cam 4th actually if you want to put in the 268 I used in 83 but it was a stock 8.5 motor and I still wipped some on the street!

    I think you will be ok with the 212 cam

    Still 8.4, that's the beginning of race gas territory.

    TA 413 on a 109* ICL would get you 7.58 DCR.

    I’d run the 413 cam, you have the compression, just make sure everything else is matched such as springs, retainer to guide clearance, etc.
    I ran one in my 350, idled at 650 to 750 rpm in gear, I could idle it down to 500 rpm in gear, idle was kinda smooth with a bit of a lope, TONS of low end torque.
    Never mind those pee pee cams :p:p:p

    alec296 i need another buick

    The 413 would be a good choice, or Atleast the 310 cam with headers and some decent porting. Better then the comps cam in my opinion. Will definitely make more power.

    if the engine is still a part you still have time to get the compression down.
    you had a Isky 262. 208-208 @.050 and it ran well in for what you wanted in your daily driver. TA-413 with 232-244 @.050 should turn on after 3500 rpms with a fair idle like to know how that works out on a daily driver. i would go up 1-2 sizes bigger then your 262 Isky, and not go 5 sizes bigger like a 413 cam. 218-218 is like going up 1.5 size bigger. i ran a 212-216 cam comp in my 340 buick mild built and then changed it out 216-221 comp cam. i liked the smaller one better down low but the bigger one did pull a little better after 4500 rpms. to do it again i would use the smaller one. ran low 14's with a 2-speed and 3.23 gears.
