Post idle-5500rpm VS 1500-6500rpm

Ok so i am looking through my Elderbrock catalog and there are different rpm speed in it. so if i went with a 1500-6500 on my olds, it wouldn't idle right? what is the difference between the two speeds. I mean there is the different higher rpm but what does it do to the idle. Which one would you recomend for street use and possibly everyday use. what would you use the other one for. Sorry if it seems like a simple question to some but sometimes there is no thing as a dumb question

You can use both power bands for the street if you really want to but the idle-5500 would have more manners on the street. I have the intake and heads from edelbrock that are in the 1500-6500 range. Basically, those numbers mean that if you add their parts to your engine, you will experience additional power starting off about at 1500rpm all the way to 6500. This doesn't mean that from idle to 1500 you will have NO power, instead it means that you will have no power gains over stock. If you get into extreme stuff like 3500-7500rpm range, then you WILL lose power from idle-3500. But thats a different story. If i were you, for the street, i wouldn't get edelbrock performer RPM cams. They are a bit too extreme. Cams are much more critical to pick out them other parts of your engine. Don't kid yourself for camshafts, buy a cam that builds power in the rpm range that you will mostly be using. This is why I picked a smaller cam than the performer RPM cam in my engine. My engine works just fine on the street. If you do buy the performer RPM cam, you will probably need to get a higher stall torque converter and gears. You will lose considerable idle quality, and possibly not have enough vaccum for power brakes and the such.

If I were you, i would buy a cam that builds power from idle-5500 or wherever you will be using it the most. It is possible to buy heads and intake for the next step up without noticing a loss in drivability quality but still get a better power gain. (but don't buy a single plane for the street)

Also, generally speaking, you will get better economy and more low end torque with the idle-5500 than with the 1500-6500.

men on the edelbrock Rpm cams. They prommised me that the cam was very sreetable, well it is, Barely! It,s not the lift that causes problems. But rather the total advertised duration of the valve off its seat. That RPM cam hosts a whopping 308 intake and 318 exhaust! WAAAAAYYYY to big for any street bruiser. Although they do have a broad tourqe curve of around 300 ft lbs and better all the way through 6500. Just expect 10 MPG and no power brakes,

FYI
Weiand has a intake from idel to 5,500 on there Stelth and Holly's 300-36 is good from idel to 7,200 1 3/4 taller like the Z28 intake.
Sorry about the wrong input the first time

I think he's talking about the Street Dominator (dual plane), a very good intake. It is based on the Z/28 intake,and is one I have used and still do.

I knew exactly what you were talking about,and I am far from a newby. I was just poking fun at your gross spelling errors probably due to fat fingering, but possibly from being totally blitzed. It was a joke.

This site is for helping out others on their problems and give them the most correct answers, I dont belive they are looking for spelling mistakes either, they just want to fix their rides. If you dont have anything good to say do, it in a email.
Edited for inproper words.
Sorry to TurboS10

Yea...and back to the point.... I had the performer rpm package on my 81 camaro with a 350 chevy. The cam had a good lope sound to it, I liked it. But I had 3.42 rear end gears with a 2200 stall converter and it was a dog off the line. Once it hit 3000, the motor came to life and put your head right into the seat. You would be good with the RPM package if you have 3.73's or higher and a 2500 stall, if you went with stock drive train, I would use the performer package. My buddy has it on his 355 chevy engine and it has tons of torque and he spanks 5.0 mustangs left and right.

hrm dyno'd em and said the rpm air gap didn't lose squat to the reg. performer down low. but a dyno doesn't go below 2500 rpm i think. i have a regular rpm on my low end truck and i think i could use more below 1500 but the drivability is not bad. i think it's more a result of my truck tranny's gear ratio's (rear is 3.50) Eldelbrock now makes a new performer model for of idle grunt. i'd like to try it. but between the std. rpm and the std. performer i dont think as far as low end grunt is concerned there is a Big dif. but i think there is some./ as far as spelling goes, misspelled words do in fact make you look like a boob. on the other hand, there is no spell check on here and who in the hell can spell all that gud aniway?
