Anyone run a .484 with a 4-speed?
Yep..
One should have at least a 3.55 rear end, we ran it with a 3.91.
Just my  .. 
I'm probably going to run either 3.91 or 4.10's.
Run a 509 w/ a 4 speed and 4.10's and you'll be close to 11's. 484's and 509's have the same "drivability" so you might as well use the big bump stick.
I already have the .484

Ran it in a stock 383 with 452 heads and 9.5 comp. It had the normal bolt on's of the RPM intake and a 750 DP. Had headers and a 3000 tight TA convertor with 3.91's. In my sons Dart at 3600 lbs with him in it the Dart ran as fast as 12.31 @ 110 ! This cam will make good power and run very good in the right combo. But I would not use it in a stock 383 or 440 with a stock convertor and 3.55's. Most people who dont like it just did not run it in the right combo. Ron

i built a 383 for a guy with that cam and 1.6 rockers. we started with a stock converter and it was not so good. with a looser converter it's much better. yeah, it's an ancient design, but with appropriate compression and converter. it's a blast. it runs crazy strong for a 383 and sounds surprisingly wicked. just make sure about that converter, among other things.
for what is the good life if not doing things thoughtfully?

 what's the right way??? I'll tell you, 3000 stall, nice headers, high compression, decent heads and 3.91's or better. So he has a stcok stall and 3.55's is it going to run well?

If I keep my stock compression, 28" tires, 3.55's, stock HP exhaust manifolds with 2 1/2" pipes and the 284 cam and put in a converter that flashes to 3000-3500 would that work for me?
Sure it will work. The point is there are other cams that may work better, although the purple shaft/lifter kits are priced better than the Comp and Hughes cams which might alse require stiffer valve springs.

I'm sure I could do better with another cam like you said, but I will need a converter for another cam too.
I was hoping not to crack the motor open at all. It's easier for me to change out the torque conveter, it only takes me an hour or 90 minutes.
Sounds like I need to change out the converter first, if that doesn't light a fire under the car then I will consider a new cam. I'm convinced this car is build to run a lot quicker/faster than it is. My small block Demon will blow it's doors off right now.
Oops, sorry for getting off the original topic.
Yes, a high stall converter will help, and likely be needed with other simular sized cams.
I have been really happy with my old Dynamic 10" race converter. The newer 9.5" converter is supposed to be even better.
As mentioned earlier, recurving the distrubitor for greater initial advance should also help.
If you have a reasonably priced chassis dyno in your area, it may be worth it to just make a baseline run with 02 sensors so you can see if the air/fuel curve is close or way off. I have seen some really nice looking big buck cars run on the chassis dyno that were so out of tune it makes you cringe.
To me, it makes no sense to throw expensive parts at a car if your not going to tune them to work right. The chassis dynos around here charge between $50 and $100 to make several baseline runs, and usually about the same amount per hour for tuning time.
The alternative is test-n-tune at the drag strip.
Tuning at the strip works, but there are so many cars at the strip here, you don't get alot of runs.

I run that cam in my GTX, 4spd and 3:54s and it works great. Bottom end and good MPG. Sounds too tame at idle though.
My sons running a 509 in a 360 4spd and 3:55s and it has good bottom end to (will ignite the tires with out dumping the clutch) and is a lot livelier than the 484 but MPG is horrible

LOL I'd rather do 3 cams then pull one trans. The 484 + moni's + stock convert + 3.55's = slow. Just get a good cam and leave the converter alone. You'll still need 3.91's even w/ a converter not to mention a good converter is $300+ and a set of 3.91's is anoher $190 just for ring/Pinion.

Tell you what you put together a stockish 440 w/ mani's, stock stall, 484 cam and 3.55's I'll do the same with and use a el-cheapo special from Summit or Jegs and spot you a light or two.

I did have FBO recurve my MP dizzy. I believe it's 18 initial and 35 total all in by 2500 rpm (plus or minus one or two degrees, I forgot exactly where it's at).
You need about 36-38* total

 Nope just been there w/ the 509 and 484 in stockish 440's. a stock magnum cam works better.
