Edelbrock heads 60049

Couple of weeks ago, Tyler went 10.71 @ 126, in the full weight red car. Mildly ported heads.

 

So what's the word on valvetrain noise?

I have only worked with the one set, was impressed with the power, dissapointed with valvetrain alignment and operating noise (roller rockers and hyd roller cam).

Now that there are enough sets out there, does someone have any experience that indicates it is possible to have a dead silent valvetrain?

I ask because I would like to add an e-head engine to the lineup here, but many of my customers don't want anything to do with valvetrain noise.

That's why we are putting a hyd cam in them in the first place.

Input appreciated.

Jim, I don't have much to compare to at this time, but our 464 sounds "mild" in the valve train area. Not silent or quiet I guess. You can usually hear the rockers if you listen for them. There is no valve train noise that can be heard above the exhaust noise, even with full exhaust.
My 462 with iron heads should fire up soon, so I can hear side by side. All other comparisons would be 350's.

No complaints from us with these heads, especially with the 10.71 on street tires.

 

rocker arm Allighnment was my biggest issue. I spent some time adjusting the guide-plates, re tightening them, re-adjusting the rocker arms. it made an improvement. now the rockers are more centered.This is the before picture.

 

Old thread now, but does anyone else have any engine build up info and track experiences with these heads?? It is nice hearing about what was done and how fast you guys are running with these heads. Seems like 11 second runs are not out of the question or overly difficult with these heads.

 

I can let you know the difference next spring! I went from a street strip ported iron head that was good for 12.60's to a set of Scott Brown's fully CNC ported Edelbrocks. He flowed one port for me and it flowed 321@.500 int and 214(no pipe) ex. The intake flow was 226 @ .300 also. Being that they are machine cut, the ports don't vary much. I went with Trend push rods and Comp's ultra mag 1.6 roller rockers and I can tell you my alignment was perfect. I sure don't know what was going on in that picture above. Valve train noise didn't seem any louder to me than the stock setup. I'm still running the same Scott Brown 226/239 cam so it will be a apples to apples comparison. The car will spin the tires at a 45-50 mph kick down now so its definitely making more power! Time will tell. In my opinion, I don't feel you can really go wrong with these heads.

Our heads were port matched to gasket. Running them 6 years now with no problems.
10.25 weisco pistons.
Stock crank, rods.
SPX intake, 950 carb.
Cam was custom ground.
We still run it on pump gas. Went mid 11s on motor, 10.71 on 100 shot of nitrous. Density altitude just over 3000'.

 

Cool stuff guys.

 

I have a set of "ready to run" heads I bought off a board member that I've not yet checked out. This info is good and quite timely to me. I'm not looking for huge HP, just got a deal on them and was planning to use them on a new motor rather than the hassle of swapping heads on the car.

Personally, porting is probably not necessary for me. I'm going to be running a TA212 cam, TRW forged pistons, Edelbrock performer and MT headers on an otherwise stock motor.

I was planning on taking the heads apart, checking the valves in the guides, looking for any obvious issues. What type of issue has anyone noticed with these?

 

if you want to beat the "new musclecars" not a bad ride to start with as it was lighter than a lot of things to come out back in the day and would say is in the same weight class as the new camaro at least,definetly a bit heavier than the stang,so you have the potential for a competitve power to weight ratio,and a 1970 455 stock wasnt wanting for torque thats for sure,but would definetly agree with the guy who advocated for building it closer to 600 hp limit you wanted to avoid over concerns of whether or not it would still be streetable.if you want to dust stock mustangs(stock 2013s make between 406 and 430 depending on trim out of the 302) especially on the street where surface condition is shaky versus the strip where its controlled,you need that power,if for nothing else than just because of how much more advantageous modern transmissions coupled with traction control and other modern doohickery(when it works)are versus the old 3 and 4 speed units
furthermore would encourage you to pursue even more power if you wanted to beat the new shelby which is putting out power in that ballpark itself and has the ability to go 203 mph stock weighing in still probably well over a hundred lbs less than your rig with the 455.would definetly advise finding the widest tires you feel you can street as well.....you know the thinking mans traction control system.
also when it comes time to get whatever monster setup you decide to put under that hood into control dont overlook the importance of differential suspension heights front to rear in order to achieve downforce without changing its overall look if you want it to look stock bodied sans lips canards and that kinda gimmick,but dont get me wrong i am an advocate for form follows function and if you are building an all out racer aerosculpt is often necessary ,and i definetly appreciate it when its done right.but have noticesd theres a right and a wrong way to go about it.
i can remember seeing things like a gt500 with a roof scoop addition and ricer cheese spoiler both carbon fiber looking at least but will just presume were fake,and worst of all hydraulics wasnt sure to puke cry or kick a puppy,really hope it was a clone otherwise someone should talk their congressman into pushing for legislation to have that considered a crime......maybe even treason.

 

Travor,

I like what you have to say.... It is tough to read without any spaces in the paragraph.... Please press enter every once and a while so we can read without getting dizzy LOL!:TU:

 

there...
paragraphs.
good?
and thanks.

 

What are you talking about and what does it have to do with Edelbrock heads?

 

I got lost there also. This is a strong thread, lots of great info. How about some mild and wild builds with the Eddy's. What was seen for performance, what changes would be suggested after the build. Loft ideas on how to be a world beater, ect..:laugh:

 

Ok..I’m THAT guy..commenting on a old thread. I have a motor waiting to be built, but in hung up on needing aluminum heads to hit my goal of mid 11s. On the list for TA, but given that may never happen, I’m considering a set of the Eldebrock. I assume there’s more feedback or others have used these heads?

 

Yes sir..that’s what I did. And ended up on this thread to bring it back. Many older links don’t show up anymore sadly.
