Hughes Whiplash cam VS MP 509 cam.

[cudaken]

 I just read up some on the Hughes Whiplash cam. Hughes web site says it will work with a lower compression motor. The 383 in my Runner right now was never intended to be its real motor, just something to get me by for a while till I built a nasty 440. Well it been 18 years now and no 440 insight. To many other Mopar projects.

Right now the current 383 has stock 906 heads, Torker Intake, 750 Holley, Hooker Comp Headers, stock Road Runner converter, R/T rear springs, 3.23 sure grip and the MP 509 cam.

While the 509 sounds great, it is a true pain in the butt to drive below 3000 RPM's. Would the Hughes Whiplash cam be a better street cam than the 509 with the 3.23 gears?

Few parts I have left over from other toys.

Old MP Hemi purple shaft 284/284/481/481 cam. I think I have the specks right.  Good street cam, very drive able and sounds pretty good.

Set of fresh 346 heads with the bigger intake and exhaust valves, match ported on the intake side and lots of exhaust port work done on the exhaust side. Reason for the work on the exhaust side these are the heads from the ill fated Blower Motor form my 69 Charger.
 
My goal is to have something that sounds good and is easy to drive. For now, just having a running Mopar is my only real goal. Going fast, I am sure that will come later as the Mopar Fire gets hotter again.

The 509 is waaaay too much cam for a stock 383 

A good off the shelf grind for that combo is the Lunati VooDoo 302

**looks like they changed the part number from 60302 to 10230702**

 Ron I am with you on the 509 cam being way to much cam, but sure sounds cool! At the time I had some really nasty 906's and the cam was to go into a 440.

What do you think of the Hemi grind cam? It seemed to have worked well, vs the one you listed?

Do you think the Hughes cam would be to much cam as well?

And finally, do you think the 346 heads would help at all, or slow down the car? It a shame they only have 75 to 125 miles on them and not uses them.

Ken,

It's easy to overcam a 383 so i'm not a fan of any of the MP purpleshaft grinds for the short stroke 383 unless you are running a loose converter and deep gears. 

Here is Jackson's Charger with the Lunati cam and 383ci with a 750 holley carb & headers. I consulted on this build and it turned out pretty descent....i know Jackson was very happy

  I totally agree with Ron here, I had a 509 in my 440 as my car was a bracket racer build when I bought it. I changed out the truck axle (Yea you read that right.) to a B Body 8 3/4 3.23 and swapped the high rise TM-7 for a six pack. With that combo the thing screamed between 55-110 and sounded evil wicked and nasty but was not practical or a great performer off line as that cam just wants low stump pulling gearing for WFO running in a 1/4 mile. Your over cammed but have what will be a very good gear.  I rebuilt the 440 and used bone stock 346 heads, 9.5 hyper pistons and a Mopar Road Runner grind cam as it matched the profile of the six pack grind. Much much better.
  Cam science has vastly improved in 45 years so it stands to reason Ron's pick for your build will have you so happy you'll end your quest for a 440 and just dial in what you have, the 383 is a very good engine!

wow his car sounded freakin mean....I run the 509 in my 383 right now  its not bad, but just initially off the line...I swear I think she is gonna bog down...then again might be my carb needs a rebuild.

 So no input about the whiplash cam?

Not on the whiplash but I have the MP Hemi one in a 383 with 4:10 gears and a moderate converter (looser than stock but not loose enough) and I'm not really happy with it.  Sounds badass but makes little vacuum and just does not work well with the rest of the package.

I may have to go with the Hemi Cam, I am on a very tight budget and I might be able to swing the cost of the lifters.

My only real goal is.

1 Get the Runner Running again with the 509 cam.

2 Sound good but be more drivable than the 509 cam makes it.

I guess the cam question came up from day dreaming about going fast again. I came a across a thread about using a Whiplash cam, so I asked about it.

I have one last cam that Denies did for me from Reed Cam's, but it was for the blower motor, I will have to look for the cam card. I think it was around 272/292/474/494. Idle all most like a stock can and ran well while I was breaking in the 440 with just a carb.

I just wish I had the flow specks on the 346 heads. That way I have a better idea if I could uses them.

The "old" hemi cam was 280/480 on a 110* lsa....definately a better choice than the 509 ! 

If you had to run that cam ; it would help to advance it to an installed centerline of 102-103* to bring the power in sooner. Very important with a short stroke 383.

I have the old 284/484 MP cam in my 440, not much of a fan of it any more.  Sounds great yes but drive ability and tune ability are nil.  Been thinking of the VooDoo cam also.  On the fence with the Whiplash cam, brothers had some Hughes cams go flat.

[69dodge383]

I looked into the whiplash cams. Decided to build my beast 440 instead. The whiplash cams are good for the street from what I have seen and read. That's why they made them.


Your 383 is fine. I think if you beefed up the converter you would see better from the 509. And the 323 gears are fine. Maybe you run locked out timing so you have more initial advance with that cam. I would try the timing lockout first and see if it helps. If it does it would be easier to do that then swap the cam and/or converter.


Keep in mind you can call comp cams and the can custom grind you whatever cam you want....

isn't 280/474? not really the original old hemi cam, but the last version ( I have it boxed yet )

[cudaken]

Original Hemi MP cam (Only Tom Hoover knows what was in the real Hemi Engine ) was 284/284/484/484.

I ran a MP 280/474 in a reringed stock bore, stock stroke 440. The car ran great with a 11 inch no name converter and a 3.23 gear.

Call jimmy at racer brown. Incredible sound, top notch performance. Some say he is old and outdated but I see lots of street cars running his cams beat the "modern" grinds all the time. His cam is still what I run in my car and it performs better then people claim it should. Its a similar grind to the mp 509 but runs and sounds sooooo much better!

[1974dodgecharger]

That's hard to beat the 509 cam I get a lot of compliments on the sound but boy she is a bitch in the cold starts....such low vacuum

[c00nhunterjoe]

2 pumps of throttle at any temp and it fires right off every time. Choke is wired open, mechanical fuel pump. Within a minute I can take off and drive in 30 degree weather. Can't rev high til oil heats up though. Cold temps it will bury the gauge past 100psi until warm.

[cudaken]

While I am still not sold on the old 509 cam, I have tried some tuning tips from Ron and throttle responses is much crisper. She does sound a little smoother now.

Road Runner had slept for 8 years and still many things to do before I start beating on her again. Around the block she feels good and will set me back in the seat nicely. Do I think this is a great cam for a street car?  No, but it will get me by for now.

Yup ken, the 509 is a hard cam to drive around time under 3k rpm but boy once u got past that u soon forget everything 


Luckily mine is a manual....

[c00nhunterjoe]

While mine was fun with the auto and stall converter, the 4 speed made it a totaly different animal. 

[Kern Dog]

I had a 509 cam in my 440/493 for several years. The car ran great but detonated even on 91 octane. I swapped in a Lunati solid that made more power but knocked worse.
If I had a 440 with less compression, that 509 would have been great.
