hello there fellas,
here is a couple of tpis hydraulic roller cams of theres listed below and wanted to know which one to get to suit the mini ram intake 1206 port size of theres also ?

ZZ-9
advertised duration 282 int, 287 exh
duration @ .50 " int 212,exh 226
gross lift .483 int, .520 exh
lobe sep 112

ZZ-409
advertised duration 287 int,287 exh
duration @ .50 " 226 int, 226 exh
gross lift .520 int, .520 exh
lobe sep 112

ZZ-9X
advertised duration 287 int, 290 exh
duration @ .50" 225 int, 240 exh
gross lift .525 " int, .558 exh
lobe sep 112

ZZ-X
advertised duration 290 int, 290 exh
duration @ .50 " 239 int, 239 exh
gross lift .558 int, .558 exh
lobe sep 112

i would be running this set up for street use running either 3.73 or 4.10 rear gears and running 6 speed manual also.
i also have a true duel mandrel 2.5 " exhaust,x-pipe,long headers,magnaflow mufflers.
also in the future soon running afr 195 cc elimanator ported 1206 size heads and custom chip with this combo.
and the long distant future to get 383 stroker crank as well.

is what i have mentioned so far a good start please for good all round performance for a cruiser/ bruiser ?

what rev range would these cams mentioned above start to kick in at do you think please ?
thank you
regards

For a streeter and if it's a 350 the zz-9 works well or the 409 would be good. The 409 in particular would really need head work, both will need new springs etc. at the mnimum, and exhaust, converter etc. The zz-9 will probably start going flat around 6-6200, 409 maybe a little better 62ish, you will really need heads or big head work to realize the potential.
I forget the port sizes off hand, but if I remember the 1206 is too big for a 113 head.

hello mseven,
thank you for the reply.
what i have mentioned wont be going on motor till i have all the good up grade parts such as heads,gears and so on.
for example i wont be running the cam/intake with 1206 size on the standard 113 heads.
and also the afr heads are good for up to .600 " of lift with there double valve springs.
ok,what about the last two cams the ZZ-9X and the ZZ-X cams would they be a better choice may be?
regards

IMO, those would be better suited to a 383 or bigger not a 350. They both have quite a bit of duration for a 350. The 9x is 225in. 240 ex. dur @50 which could be made to work but would present tuning issues and as to streetability, would probably not be much fun from light to light would also need a big converter etc. The X is worse with 239 239@50 that's a pretty resonable cam even for a 383.
If your putting it together as a 350 and it will be street driven,the biggest I would ever go would be about 220in. 230 ex. @50 112 lsa. If your sold on the TPIS cams or buying their upper end package, the 409 is probably the better comprimise for an all around street car 350. MO

emo-vet,
the .558 lift is probably a 1.5 ratio figure, ending with 1,6 ratio to .598 lift.
and do a search for TPIS cams on the forum. I read that someone performed some measurement on lift, durations, LSA and intake lobe ceterline, resulting in very different values compared to the declers specs by TPIS.
A custom grind from Comp Cams should be the right choice.

ZZ-9X would be the smallest I would go, and if its street driven alot, on a 350, thats what you should run.

Edit, i mean 409 is the smallest i'd run

i would go with the zz409 and have your eliminators set up with beehive valve springs and titanium retainers, this along with some quality roller rockers will push the peak power to about 6800 to 7000 grand. i had the tpis zz409 in my car and it peaked around 6300.

i currently have a custom grind from comp cams that is pretty close to the zz-x in my 406 sbc and i am not happy with it. i drive my car to work everyday, the idle is pretty choppy, minimum set idle is 950, and it's been a pain to tune. when the car sits at a light it's pretty loud and lunges too much. i also have some part throttle hesitation. You can tune some of this out, but eventually you run out of options, it's a big cam, you have to live with some hesitation. alll this goes away when you have your foot to the floor and tach out. this is the only time i like my car. this cam seems more of a track only cam.

i will be putting the zz409 back in along with beehive springs and titanium retainers. it does have a lope at idle but it's cool and mellow not choppy at all. this cam idles pretty well at 800 to 700 rpm and has plenty of vacuum. this cam is a lot more streetable.

a while back i was selling my zz409 cam, i'm so glad that nobody bought it.

one more thing to consider, it's all about how much you are willing to live with. if your car is mostly a saturday sunday car and you are willing to put up with a lot of the pains i described about a big cam, then go for the zz9x or zzx. if you drive your car to work and drive it frequently on long trips, get the zz409.

there are some members here that have way bigger cams than the zzx and swear up down that theirs cars are totally streetable and that they don't mind all the hassles associated with big cams. like i said, it's all a matter of how much you are willing to put with.

forum member mos90, has also had all those cams that you listed, maybe he will chime in. pm me if you have more specific questions.

I'm thinking the ZZ9 and the ZZ409 would make it well with a standard 350. The ZZ9X and the ZZX cam would be definitely suited for a hot street 383. I wouldn't overcam because you'll have barely any vacuum for your vacuum power accessories, e.g. brake booster and HVAC system, plus street manners would be terrible.

hello again fellas,
thank you for all your help and advice r.e tpis cam selection.

currently i have a comp cam 268 xfi roller cam in these specs
advertised duration is 268 intake,276 exh
duration @ .50 " is 218 intake, 224 exh
gross lift running 1.6 ratio is .570 intake, .565 exh
lobe seperation is 113 degrees
and rev range is 1,800 rpm up to 5,800 rpm.

this being said i was thinking that this cam would not be any good to run with a mini ram intake thats all and was looking at tpis cams.
thanks fellas
regards

go for the zz409 with the above mentioned valve train upgrades with some good flowing heads.

mseven

those numbers are pretty close to the zz9 or Hot cam, which would be fine. If you have this cam and good rollers already I'd put the money towards the heads now instead of buying a cam. When you go to a 383 a cam more suited for that would be a bit large in a 350 build. MO

pushrod-v8

missed the part about your current cam. Keep it and focus on a GOOD set of cylinder heads and valve train components.

emo-vet

ok cool, thanks
i will keep the cam i got then.
also i do have 1.6 ratio comp cam roller rockers as well already for new heads.

I am running the ZZ9 cam in a stock bottem end 350. Good results so far. I am also running a TPIS chip, car seems ok on the street.

Anyone running the ZZX cam in a 350 ?

Vic. I think the ZZX is too much cam for a 350.
