TIME FOR POWER (Heads, Cam, Intake)

[pgriffith]

I have hear its about 40 RWHP. Thats about what everyone seems to be getting. Maybee somebody with the kit can tell you better #'s but thats what ive heard.

[Camaro15]

I have a 94 3.4L, what kind of stuff would you recommend for my car that would get it close to our above 250rwhp without getting too expensive and complicated???

[veesix]

Ricecooker gained 30 hp without any type of tuning. He dynoed at 160 rwhp and after the kit he was at ~200 rwhpAfter you fine tune your system it should be more maybe another 20 or so rwhp.

Hey magnus could u recomend a heads and cam package for me. I want it to be a daily driver but i do like an engine to lobe. I have a 70 chevelle I love it. I will be using this cam with a NX wet setup so what specs on the heads and cam should I get also is Porting and poilshing the upper and lower intake worth it especiallt for nitrous

[Magnus]

Hmmm... thats a tuffy...

Using COMP Cams Xtreme Energy profiles:

Shooting for a split duration because of your nitrous use..

206/212 would be nice.. driveability would remain very good while NA power would still increase as would N20 power.

212/218 , the next step up in split design... driveability would be a little less decent but I bet you would make more power with this cam using N20...

For a daily driver and not wanting to deal with many hassels like driveability issues, I say the 206/212.

You culd go with a 212/212 symmetrical duration type cam which should do very well NA and also very well N20, but typically N20 likes an exhaust favor. BUT our heads do flow very well and if you have headers and a cutout, a symmetrical duration camshaft should work nicely even with a power adder.

I plan to spray with my 212/212 cam.. I'll have ported heads, RK SPort Headers and an open y-pipe so I'm a little less worried about exhaust flow.

magnus tom sent me a desktop dyno of wht my cam would put out he says 277 at 5500 rpm right where i can use the power :D PLUS MY PEAK TQ IS RIGH AROUND MY STALL SO ITALL WORKS OUT. sorry 4 caps

[slacker69]

Thanks magnus i have the headers going to a 3 inch setup and when they weld i am putting in a cutout after the high flow cat. So when u say less drivability what are u meaning like it will have a rough idel cause thats not bad girls like the rumble in there pants right. Cause i would be willing to try that other cam u said whould be better. also on the heads i need to get new valve springs and retainer locks right.

magnus i have been looking for a way to get a hold of tom do you an email addy for him i have a cam thats from crane cam powermax2030 is this a good cam what do you think 94 3.4 auto. What should i expect already have it so let me know before my chance to send it is gone. Thanks
here's the link to the cam Also i'm port and polishing with a three angel valve job http://dab7.cranecams.com/SpecCard/D...1=Display+Card

bluecmaro96, I do not trust Desktop Dyno.. I wouldn't live my life by it either. Use it to graph Mike Huff's dyno with his 210/214 cam, I bet you they don't compare right.

Driveability like.. there won't be enough vacuum for the brakes, the idle will be very chopy and might die out on you when you slow down to stop.. might be hard to start.. things like that.

Really, the best bet would be to wait a few months till a few of us get our cams in so we have a better idea of what happens.

Sorry but any recomendations for the 3.4 would be merely guesses.

[-red97rum-]

hey magnus, would you be able to run a 206/212 cam with stock springs? Or a 212/212 I probably won't put n2o on my camaro... well not sure yet but I just want a little more umph, I have a '68 chevelle SS w/396 that I am trying to build, so that is pretty much going to be my weekend street racer and little girl (mustang) eater. but anyways what approx. gains would I see How much would it cost-guestamation?? thanks for any info! :D

Lift not duration is what destroys springs.

[RiceCooker]

these are the specs on my cam:
210in/214exh 112 lsa .450/ .450 lift

I have stock springs still, and there have been no problems. Although, IF I were to rebuild the motor, I would get the titanium springs from Thrasher, just for peace of mind. I would strongly recommend them, even w/ a .45" lift, if you plan on using a poweradder. This cam is very drivable, has a nice lump, and Tom says it will be good for juice.

[predator5100]

Magnus thats fine what kind of guess are you thinking for my cam also i think my crank is walking back and forth i'm chewing mounts and it comes and goes (vibration)

[Magnus]

I'm sorry but I really can't guess.. The 3.4 has a very wierd cam imho. 109 lobe separation with a 111.5 intake centerline.

Your best bet would be to talk to some 3.4 guys or call up COMP Cams. They are very helpful. If you tell them what you have and what you are looking for, they can better recomend a cam for your application than I can. Sorry.

Choosing a cam is a very risky thing. There are so many combinations, so many ways to fail... If you take the approach of.. I want the most.. I want more.. Gimme Gimme Gimme... I want all out cam.. then chances are you are going to have a cam that shakes the hell out of your car and makes no power.
