Performer RPM intake and Cam

[Questions]

I purchased a Edelbrock performer RPM intake for my 1969 340. I am wondering if the matching cam( dyno matched kit) is a good cam for my motor.The motor is bored .030 over, but is basically stock. I would asume that it is a good cam, given the fact that Edelbrock has done dyno tests on this set. Does anyone have this setup?
Any help is appreciated.

Did you look at the dyno runs on their website?

[pishta]

Let us know why they say to use their timing gear only. 397 HP out of an untouched iron head sounds good to me with that setup.

[Questions]

I didn't know the posted them, I just looked through the summit catalog.

Diamante, great car until it breaks down. Sold it when the ignition started acting up for no appearant reason, stranded me twice in two days.

i have a Performer RPM and the Mopar .474/.474 lift cam in brand new 440, it isnt even in the car yet, how does that sound?

[Questions]

Roger,
I looked and could not find any prices for those heads. Also could I use any of my stock springs or rockers.

I am using the exact set up with the 7177 cam, I can't tell you how it runs because it is not in the car yet. But the dyno #'s looked good to me. I fell that this is a proven combo. My friend has the same set up only with the E-brock Heads 417hp.

Dave....

From summit:

bare small block chrysler heads (60769) $544 on back order
assembled heads (60779) $635

prices are each

As you may have read on here, that sometimes people get heads with poor valve jobs or they want differnt springs with more load on the valves. If you are going to want perfection from your heads, buy the bare and have a good shop do the work for you, with the right parts. Otherwise, the assembled ones will be good for you.

[Questions]

Diego-ted,
That sounds pretty good. Please post something when you run the engine.Are you running a 727 trans?What stall will you be running on your converter?

Thanks,

Hey Roger do you have any numbers on what those heads flow. Is it greatly increased over stock and are they good for regular pump gas. I am inquiring for my 71 318. I would like to get it over the 300 horse mark and I have a Performer intake on the way right now. My cam selection is still up in the air. Do you think that a performer with performer cam, mildly worked 302 heads and 800 TQ would work pretty good together?

[6 packin]

The Edel Cam specs are 234/244 Dur@ .050 lift. Thats a strong cam with a definate rough idle. I have run the similar Comp xtreme cam which is 230/236 @ .050 lift. That cam will make great power. I hope you dont have power brakes? It will idle just below 1000 rpm's. You will be making distributor adjustments for sure if your running stock cam and egnition now.

[71SATELITE]

Hey sixpackin I have manual brakes and plan on keeping them. They do not bother me I grew up driving these types of cars. I like the sound of that eddy cam do you have a part number? Mabye Roger H can stick one in his pocket for me on his way out of work one day. I just converted to MP electronic distibutor and am very happy. It is even curved right on the money. My points dist. have way to much advance. Like a total of 30 deg mech, (ping!)

[ehostler]

I said this in another thread, but don't buy an EB cam. Get a Racer Brown or Hughes cam instead. They were actaully designed and ground for a MOPAR. The EB cam is crap and was designed for the small lifter bore of a GM.

[Questions]

I have manual brakes on my cuda, and I'm glad to hear that you are happy with the specs on the cam.
71 Sat.,I was wondering how much of a difference you noticed with the electronic dist, I am on single points and am having some advance problems.

The Hughes HE3038 cam is about the same duration at 0.050", but a faster rate of lift cam designed for the Mopar 0.904" diameter lifter.

Dave, I will be running a 727 with a 2800-3200 stall. I'm only going to be running 323 sure grip in the back, because I want to do some highway crusin as well as some strip. Being the fastest is not my over all goal. I just want to smoke the ricers when I want to. I guess the best case would be to get some 390's with the overdirve, but muncho $$$$ so this will have to do for now. Should be ready in a week or so. I am changeing the whole drive line motor to rearend. had a 318, 904, 71\4 non sure now

The 397 HP rating is before Edel. produced there heads for the S/B Chrysler. The heads were worked on a bit. There "Package" is just what they did. If you want 397 HP useing there set up, do it.
Change the cam around for different power gains/loses depending on the RPM you drive in.
Less cam equals more torque/less HP and a larger cam equals less torque/more HP.
Edelbrock made there cam to fit into the RPM range of there intake with the street crowd in mind. A larger cam could be swap in place of there cam and still work well. There cam is not a must, but there idea to create a nice street engine. Good HP and torque for the street cars.
A good cam because they dyno matched it? Not really. Just one they selected.
CHOOSE a cam based on the RPM you want to cruise in.
I think you can do better than an Edel. cam.
I have not heard of any quality control issue's with there cams. So in that reguard, there fine.
The way there ground, other cams take advantage of the larger iffter MoPar has.
This advantage, if taken, will make more power with a smaller Adv, duration cam.
The addition of there alum. heads helps even more. Boosting power to 417 HP is nice.
There heads are equal to redoing your iron heads with work. Chances are you'll spend more on your iron head than you would purchasing there heads to get the same power.
IMO, it's a good deal.

[diego-ted]

Thanks Rumble, I asked everyone's Opinion on the board when I was doing my set up "on a budget" Since this car will see 80% street use and only runs on the strip maybe 4 or 5 times a year. I thought this was a good set up. I know Ed pushes Racer Brown cams and they are probably better in the sence that they are ground for exactly what you want to do. But I got such a good deal at the fall fling on the cam and worked X heads with the matching springs, I had to go that route. What do you guys think of the gear venders over drive?? this way I could run 390's while in town and on the strip, but still have good hiway crusin.
Thanks

It is not difficult to build a small block 340/360 to make 400 Hp, even without using the Edelbrock heads! The Mopar mags has done it a few times over the last few years. The run on pump gas also. The orginal X heads flow very well, they hav been known to flow with the Big Block Heads on the same flow bench. The later heads have the same intake runners as the old goodies. except the small 1.88 intake valves. The engine is question all have had big valves and the bowl openings under the valve open with usally nice deshroud and 3 angle valve job done. This late 70 smog 360 made 400 hp and 400 ft/lbs of torque.

[ehostler]

I've just done my research and found that the Racer Brown and Hughes cams are superior to the other brands, for about the same money. Heck, I would run a Comp Cams before I would even consider an EB cam.

If you search through the threads, you will find one, where RogerH (EB engineer) also says to stay away from the EB cams.

Roger H. Rebuttal please. Whats the scoop or poop from your point of view.

I am no cam expert, but I have a little bit of experience with Edelbrock cams. If ours is the type you are looking for, it will work fine. When I had a boat, with a 455 olds in it, I put a performer cam in it (this was LONG before I ever thought I would be working here!). It worked great, no problems what-so-ever.

If you are the all out type of performance guy, I wouldn't recommend a Edel cam. A hydraulic roller made by a cam company will work better for you.

Edelbrock is all about a power package, and our cam works great with our package, but if you want something a little or a lot different, then by all means select another. Our parts will still work good (heads and manifold, etc).

We also add another point in the distribution of our camshafts, since we have someone make it for us. So it will probably be on the more expensive side.

If you want to talk to someone at Edelbrock with the most knowledge of Mopars, call the techline and ask to talk to Smitty.

I've been reading alot of threads in here and am not seeing people recomend MP cams. Are Hughes that much better?

[71383bee]

MP parts in general are having huge quality control issues. If you search you will find some people that have had notthing but problems with their cams. Another huge factor is that the MP cams are just old school technology. Hughes and Racer Brown are probably on the fore front of strictly MoPar style cams. Check out hughes site it is pretty informative www.hughesengines.com

Comp cams has gotten a negative rap because they are a larger company the designs their cams on a Chevy style lifter which is smaller than a Mopar lifter. I have heard that they are coming out with cams specifically for the MoPar lifter though. I am running an Extreme Energy cam now and so far i am very pleased.

[pishta]

That combo if you are still interested just shows what a .030 over 340 can do even with off the shelf parts. 397 HP with 3 angle iron heads is pretty good. I dont know if spending $1200 more for 417 HP is really worth it for the RPM heads unless you want to go bigger in the future. Oh Lord, when will it stop!

[ric the swede]

What about Ultradyne tight lash cams that Muscle Motors sell?
Anyone has an opinion of them?

[DartGT66]

Ultradyne tight lash solids are every bit as good as the other "mopar" cams, if not better. Comp Cams also has a new set of high rate hydraulic cams for mopars, that according to the specs can meet or beat the Hughes grinds. I have not seen any numbers for the racer brown cams, but every cam grinder can grind anything you want. For example comp cams has several lobe designs in their catalog where to choose from, and there are very aggressive designs too.
