Take a look at the Lunati voodoo cams.On the site there is a video with Thumpr,Mutha Thumpr and the Big Mutha Thumpr.From mild to nasty choppy idle.

The voodoo's are street cams,They were made to give that muscle car sound with good street manners and have a increase in performance.Not full out race cams but I'm with you on the the choppy idle without a loss in performance.I would match the combo with the springs Lunati offers with these cams.Just my opinion.

what about a 4*4 cam i can you run those with stock springs? If i change the springs is that something i can do in my garage or do i have to take heads to shop

I just bought an Edelbrock Performer RPM cam and lifter kit with 234/244 degree duration and .488/.510" lift and they will increase my power and be pretty choppy. I'm also putting on an Edelbrock RPM air gap intake. I got both from Summit racing. The cam and lifter kit was $169.95 prt # EDL-7102. The intake was $218.95 prt # EDL-7501. I hope that helps a little. Good luck.

I recomend a lunati bracket master2 cam kit such as P#00016LK it has a.458 lift or 00017LK it has a .460 lift this is the biggest lift I would use with the 882 heads being that they are not a good performance head.
For the springs it depends on the outer diameter if they are larger then stock then it will be a job for a machine shop.

Ditch the 882 casting. They are a thin casting head and are prone to cracking especially in a performance situation.

I'm Installing a set of 305 heads with 1.94 exhaust/ 1.60 intake, Z28 springs, screw in stud mounts,guide plates, and 55cc chambers. I bought them from Clearwater cylinder head inc. for $500 shipping included. Their number is 1-800-572-1963. I also bought a set of Harland Sharpe roller rocker arms w/1.65 ratio from summit for around $230. If you go this route I would also look into a set of Z28 push rods because they are stronger than the stock ones in your car. Again good luck. P.S. this is just a cheaper route not necessarily the best.

thanks for all the responses so far so even though these heads are practically new i need to change them? ive heard 882 are the best of the smog heads good flow bad compression is that right?  Now its a every day car but i do do a little street racing so whats the best route getting some vortec heads? motor has been in a car a month or so i just spent alot to get that done so trying to go cheapest route but want to do it right way because motor has around 450 miles on it

You dont "need" to change those heads. Youll just get a far superior head with vortecs or an aftermarket pair(AFR, Trick Flow, Dart). You could port and polish those 882's but you would still get better flow with the heads mentioned above. With the vortecs yould also need an intake to match them since the mounting bolts are different.
Stick with what you have, save some cash, get a better set of heads when you dont think it has enough power or you start losing. Also, dont street race, race at the strip!!!

Don't sweat changing your heads if it's a street car.  You want a cam with less LSA, the cam you have would lope hard with 106 LSA.  You could have crane cut one for you.  The Thumpr by comp is a good choice as well.  If you put in an aggressive cam you can expect to lose a little bottom end in exchange for some top end.  Get a looser converter if you change cams and lose a little bottom.  The Comp 270 H is a good street cam that lopes pretty good.

ok some of the cam you guys are suggesting seems smaller  than the cam in here now its valve lift is 467 int/exh  222/222 @ 50 power range 2000-5800. am i reading specs wrong so if i can run this without stall i should be able to run a voodoo right

i want the clean cackling sound more than the lobing

If I am not wrong.I believe you speak of the sound of higher compression and a cam to match.The crisp sound you speak of will need more than just cam.Then again what you hear may not be the same as I.

yes thats is the sound i speak off, so heres what im thinking get crane cam 274H06 218 @ 50   450 lift  
106 lsa. And get a set of vortecs from the yard that should give me the compression.I should be able to use stock sprigs with that lift and the 106 lsa should give me the sound


will heads from a regular roller 350 with some thinner headgaskets be enough because i have some of those
