TPIS ZZ-9 cam vs. LT4 Hotcam
anyone got any suggestions. i know the hotcam is a very good streetable cam and i like its sound.
ive heard a ton of good things about the ZZ-9 cam too.
the car needs to pass emmisions. im planning on doing some mild headwork including 2.00" intake valves. also all supporting valvetrain upgrades of coarse.
here are the specs if anyone wants to glance at them quickly
Hotcam with 1.6 RR's
218 / 228, .525 / .525 112 LSA
ZZ-9 with 1.5 rockers
212 / 226, .483 / .520 112 LSA
im looking for near 400 horse with other bolt ons and all that stuff. i e-mailed TPIS and they said a zz-9 should make that much with some good headwork and bolt-ons. anyone got any oppinions or suggestions on this....

Well the ZZ-9 would be easier to pass emissions, but the Hot Cam can also pass emissions with the proper tune. I don't think that they were talking about 400 RWHP because you're not going to get there with either cam. I would go with the Hot Cam since it has a little more duration. With ported heads, headers, cat-back exhaust and a good tune you can expect 370-380 RWHP. Good luck.

Honestly I dont like TPIS's stuff at all. The guys who run thier cams around here dont have good times or numbers from them. One of which was a ZZ-9. Judging by the amount of propaganda I see in their catalog, I wouldnt trust their judgement personally. I'd go with the Hotcam out of the two. Talk to Bret Bauer, he might cook something up for you thats better than both. I'd also look into the CC305 for emissions. I wish I i knew if the GM 846 could make it cause I like it alot.

Re: TPIS ZZ-9 cam vs. LT4 Hotcam
sorry guys FWHP. sorry for any confusion. im hoping for a streetable mid 12 second car and then im gonna spray after its all tuend and running properly. i was just thinking about those two cause they are very common and would be easy to tune and the hotcam kit is a pretty good way to go from my point of view. i havent heard anythign bad. guys think mid 12s are possible with a hotcam, headwork and supporting mods? i got mods in sig. planning on total valvetrain swap. headwork with 2" intake 1.56" exhaust and then mid lengths, injectors, and whatever else anyone can suggest.

Re: TPIS ZZ-9 cam vs. LT4 Hotcam
I think the Hotcam/Heads, and supporting mods would easily net you mid 12's if not very low 12's. There are a few who can pull mids 12's with bolt ons, and many who do it and 400 engine HP with just a cam. You being a M6 makes the car easier to street. If you on a budget I'd look at getting the right sopporting mods and possibly a nitrous grind cam since you might plan to spray. Darkhorse runs a GTP 4 blower/nitrous grind in his car with bolt on's and has seen a best of 12.3 at the track. Perhaps, as I said before contact Bret Bauer and ask him what he can do for you. One of his cam only cars with shorties, and not near full bolt on's put down 352/35X at the wheels. If your not on a budget I'd just call up Lloyd and say "Give me a LE1/LE2 please. Good Luck.

I am running a copm 218/224 exe and it works pretty well. I actualy replaced my hotcam with it and think its much better.
Also take a look at the crane 210/224 if you are looking for an awsome small cam.

HOTcam, some headwork and bolt ons will definitely get you 400 hp at the crank. Mine passed emmissions no problem here, I did have a random tech high flow catalytic converter as well. Mid 12's should not be a problem either.

I'm going to chime in also and recommend the LPE 211/219 .533/.560" with 1.6s on a 112 or the 219/219 .560/.560...Both are great small cams that make big power and pass emissions.. I had the 211/219 in my 383 (which everyone said was way too small, but I guess John knew what he was doing....) for 10 years with ported stock castings and 2.00/1.56 valves...Always ran high 11s at 118 in good air, and always passed MDs strict emissions. All of LPEs street stuff has to pass emissions and does...My Firebird ran cleaner than my Pathfinder and got better mpg, too...

Re: TPIS ZZ-9 cam vs. LT4 Hotcam
well the goodnews is right now the car runs really well (knock on wood) compared to a lot of other LT1s around here. doesnt miss a beat always has the power when i want it but of coarse i want more.lol. i can get headwork done VERY cheap. im talking 300 bucks for a bigger valve job and some portwork. basically i want to be under 1500 for heads and cam which i dont think will be too difficult.the car has 120k on it right now, and when i do the heads and cam ill prolly check the plugs and keep using them if they're good. a hotcam with nitrous will work fine wont it not? i plan on running prolly a 100 shot with all the safey items prolly only at the track about 5 times a month say, only during track season. what other bolt ons would be a good idea. right now i want to do a CME with MAC mid lengths, and keep the cat for emmisions but prolly take it off after i pass. besides headers ill prolly do some higher flowing injectors and a PCMforless tune. what else is there to do when u do H/C swaps? car has gone 14.1 at 99 w/ 2.2 60' with free mods, CAI and turndown after the cat. any help is awesome, looking for any oppinions.

Re: TPIS ZZ-9 cam vs. LT4 Hotcam
If you're getting head work done, why use an off the shelf cam? For $, you can't beat a cam made for your purposes.
My opinion only here - if I had 120k on the clock, did a h&c swap and all went well, I really wouldn't push my luck with the happy juice.

Re: TPIS ZZ-9 cam vs. LT4 Hotcam
yea, like i said though if i do decide to install a kit and use it it will be mostly all track use not all the time even. does the Hotcam kit come with SA rockers? dont you need NSA rockers to run guideplates or am i trippin here? i was thinking about getting the kit and then buying the extra valvetrain upgrades to go with the kit ie. guideplates, hardened pushrods, then the valves and stuff for the valvejob.

Re: TPIS ZZ-9 cam vs. LT4 Hotcam
Yes Guidplates are only to be used with NSA rockers and Hardened Pushrods. Now with the Hotcam kit, I'd invest in some hardened pushrods, the basic set from Comp is like $35. You wont need much extra with the Hotcam Kit, its basically made to drop in and run. Well, with other mods and tuning of course.
