I have a chance to pick up a 284 484 purple shaft for little or nothing and was wondering what your opinions were on this cam? I would be putting it in a 72 Rrunner, 440, stock with a performer rpm, 750 vac sec holley,headers, auto, 323 rear gear. Will it work and if not what would I need to change? I know there are better cams out there, but like I said this one is easily available. Thanks for any advice!

buy it/install it 4 deg adv w a multigroove timing set/break it in w new lifters per "breakin secrets" at www.mototuneusa.com. Assuming your 440 is a low comp one w the pistons ~.100 in the hole so no possibility of VP interference/call it good.That'll change your idle vacuum so to get it spot on retune your dist; initial/total/springs/vac adv in order then attack the carb

You will need a decent(3000 stall) converter and better than 3.23 gears to make use of that cam. Cheaper to buy a grind that matches your combo than to buy a converter and gears.
Very good advise

Will it be ideal with a stock converter? No. Can you get by with a stock converter? Depends on what you can live with. It will likely idle a little above stock at 8-900 rpm so when you pop it in gear it might be a tad harsh. It MIGHT be a little lazy getting away from a light but with it installed 4 deg adv and with a 3.23 I doubt it would be an issue around town, like it will roll out 10 feet and then blow the tires off it. If you can make those compromises, you will be grinning. On the highway it will be a none issue, just grab 2nd (up or down) and wave good bye.
A buddy of mine has a 74 Challenger with a basic 440, 727, 3.23's and that cam. With the so-called factory hi-stall (2200 rpm?) he runs 12.90's

I ran the big Summit cam in my 440 for a few years.Had a nice lumpy idle pulled hard.I run a 4 speed so convertor wasnt an issue.Pulled it and put it in a 383 probally 20 years ago.Its still going strong.I also ran 4.88 gears when I had it in my 440.Rocky

Car will be mostly street driven and will run a looser conv. at a later date. Just wanting good sound without totally loosing my low end.
sound is over-rated. And you will loose all low end. That cam doesn't start working until 3200 or so.

The 484 cam (if it's the old style) can be a dog in the wrong combo. I had a similar set-up in a 440 coronet w/ 3.55's. The car sounded great and ran like heck after 3500rpm. It had no low end. I was running a 175 convert and yanked the cam and went w/ the summit 488, it ran much much better.
What did you have it dialed in at?

I want a hughes whiplash for my 440 its got the lumpy sound and is made to work with low comp has an early intake closeing to build cyl pressure and not kill off low end torque works with stock verter and 3.23s would be good for the street great cruzing cam with some pop for red light to red light action a more modern cam just for a low CR street engine would be the wize choise,IMHO my

There's no magic in a "whiplash" cam. Sorry I couldn't help it.

I know but it is a very nice sounding cam and does work well in a lo po engine on the street way better than the lunati 292/292 worked in the stock sb 360 it runs circles around it I am sure there are others that work just as good if you campair the #s me picking them out of a hat,hands down its been the best one in my stock junk

no idea motor came in the car. 484 and 509 are good cams, but they like compression, head flow, gear and converter. I wouldn't use either in anything less than 10:1, 3000 stall and 3.91's.

No intention to steal this thread, but I changed out the 284/484 MP cam in my newly built 451 low deck w/ 440 source kit & eddy heads, for an Engle AMC grind K56/K58 cam w/ 112 lobe separation. I wonder from reading this, if I made the right choice.
so if I'm reading their website right that would be 504/514 and 224/230 @.050??? should run good. What is the stall and gear? I'd think you'd need less stall w/ that cam than the 484 and you'd want at least 3.55's, 3.91's would work better.

I would be willing to bet the guy that installed it just did a "dot to dot" on it and it wasn't even close. Too bad you didn't check the dial on it before you changed it. You might have been impressed.
Kind of an apples to rutabagas comparison but I run the .509 in my 8.97:1 493 in a 4800 lb. 66 New Yorker. It's the 108 LSA installed straight up. It made over 500 ft/lb from 2000 to 5500 and peaked 600 ft/lb @ 4000. Idling at 1100 was a pain with the stock converter but I had no problem breaking a motor mount in the driveway seeing how much all that torque would increase stock stall speed by. I ran a 2800 Turbo Action converter after that and it drives around town just fine. The only time I took it to the track, it went a no traction 13.92 at 101 thru full exhaust with a 2.76 SG on regular gas. Considering the difference in cubes I would say the 484 would have the same street manners in a basic 440.

So what kind of gains am I looking at by advancing 4 degrees? Just curious if it is worth purchasing a new gear set as I already have a new std one. Thanks again!
Anyone?
It is worth the price of new chain. Advancing the cam 4 degrees gives great low end torque.
