Funny how folks are different. I would much rather swap out a converter than do a cam swap
Of course it probably helps that I have a two post lift in the shop. I would hate to do a tranny swap on jack stands again.
That'd be me

I think I'm one of the guys who would rather replace a converter than a cam, too. Maybe that's because it seems easier to work under an A-body than under the hood of one with a 440 up front.
My setup was far from "optimal" in the sense that it wasn't going to get the quickest quarter mile times, and it wasn't perfect to live with 100% of the time, but it WAS pretty easy to drive on the street. The engine was/is a 73 HP unit with stock replacement pistons, i.e., way down in the hole. I'm thinking 8:1 is hopefull... Intake was an OEM iron unit from 68, and exhaust was the good old Hooker fenderwell units in 1-7/8", gears were 3.23's, and the converter was a super tight 11". Idle in neutral was about 1000rpm and maybe 12" of vacuum; idle in gear was 750-800rpm and maybe 8" of vacuum.
Was the bottom end a little softer than with a Magnum/Super Commando cam? Probably, and thankfully so. I still had to feather-foot the car out of the hole to get it moving quickly, and any type of acceleration contest was better attempted from a roll. It was great for impressing my friends, though. Tire spin? No problem. Hang the tail out? A quick half-throttle got you there. I knew I needed a looser converter, but I just knew there would be a lot more "sit-n-spin" going on if I did change it out.

well replace a converter is a heavier work, but less bolts involved, no gaskets and cleaner job.
Replace cam will mean drain water, remove stuff with gaskets that could need to be replaced, if A/C equipped probably you doesn't have a recover can so will lost it, remove radiator and condenser if thats teh case, more lines etc...
all depends at the end if you are concious that's what you want because you really like the cam

Haven't you been paying attention? He doesn't USE logic.
In his eyes, this cam is junk because HE has never had any luck with it. If he were utilizing any logic, he would have read of the SEVERAL others who use this cam with success and realized that it's a decent cam. THEN and only then would he start to wonder why it seems that only his set-ups were dogs.

I too have the 108cl 284/484 cam in a built 383.(12.5 trw's w/ported 906's,RPM intake,1 7/8 headers,PTC 3000 converter) I've been trying to get it to run better for the past couple summers and have only been able to pull around 9-10in of vacummn at idle (6-7 in gear)and still have terrible power brakes! I think some of the problem's is in the carb but one major inprovement's came from yanking one of the dizzy springs out completly! Atleast now its a million times more responsive than it was. I have no idea were the timing is at, I've been retarding it more and more and it actully runs stronger and stronger! Bottom end is better than it was too! I know I need more gear as its only got the 3.54's in it. I think next Im going to step up to a 850dp holley and try that instead of the 750 vacummn sec. one on there.
I plan to keep tuning on it over the summer. Over-all its not a bad cam to run............but there's got to be better one's.
I'm going to suggest that after reading your tuning description you have alot bigger problems to worry about than a cam swap....
//////////////////////////////////////////////////\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ To defend myself alittle, I understand that my combo has some flaws, but last year alot of members on here suggested diffrent things to make this combo work as opposed to swaping in a diffrent cam. The major consenses was that I need to look into my distribtor and that by pulling out one spring I should see a diffrence. WHICH I DID, and since, it has made driving the car a ton better I just moved on to bumping the dizzy one way or the other till the car started with a bump of the key and where it seems to PULL the strongest! GRANTED, this is not the proper way to "dial it in" but this is what I've done to "get me by" and get the car on the road. The car actually runs real good but I know it needs more ajustments to reach its full potential, but NOBODY AROUND ME IS A MOPAR GUY.........mostly CHEVY guys and they offer advice..............but basically Im on my own~
The motor is NOT an actual 12.5 to one motor.......Thats what the TRW (piston) tech guy said it would be with the CLOSED CAMBER heads, He also said it would be a "point and a half lower" with the opens, so its probably in the 11.1 range. Basically my post was a cry for help, as I have no-where near the experience you guys have............ Thanks for your response though.

My RR is setup as a protouring type car seeing lots of regular street duty in cities. With the old 284/484 cam in a 383 it is certianly street friendly but it is important to get it in the right combo. And I ran 13.2 at almost 107mph on low profile street tires in the car so I would say it certianly can make plenty of power & work on the street. Of course mine has a real 9.5 to 1, 3.91 gears and a stick with no need for vacuum which is good because I could not get anymore than 9" of vacuum out of mine. Todd

They are poo poo dog cams. Unless you have a3k stall, 3.91's 10:1 (or better) good exhaust (headers)RPM intake (or like), good carb they are dog cams. They don't pull until 3k or better, make no power down low. If you have all the above they will work pretty good however they are not a good street cam. They have terible idle quality and pull zero vacuum.
Great assessment. Just not ACCURATE.
Have you ever actually ran a 484/284 in a car? Give us the specs on the engine.
I've ran a ton of them, my Demon had the P4120235...
LESS than 10.1 to 1 compression Pulled VERY good down low. (with a tunnel ram and 2x4bbl too) Made tons of low end power. Idled solid as a rock in neutral and in gear. EXTREMELY drivable, it was a great package. Pull "zero" vacuum? Get real, my Demon had POWER BRAKES, it never had a hard pedal in the 10 years I regularly drove it on the street.
The car was fairly well known as I had it out all the time, in the middle of winter in 6" of snow even. I drove it year round for close to a decade. My wife went shopping in it quite a bit.
Could it be you guys who don't like the MoPar Performance stuff are setting up your cars WRONG, then blaming the parts instead of the tuner..?
Take a look- 484/284, tunnel ram, two four barrels and it passed AirCare emissions testing without detuning at all every single year, from 1991 until 2000.
I raced alot of cars in that time in the lower mainland of B.C., ask around how poorly my combo worked, most people asked if the car was a roller cam, and we would all laugh.
Makes sense to me!!

The name of the game is to make the parts work in harmony.

My GTX has the 284/484 Mopar cam. During recent discussions on the board I was told by many that they really disliked this cam (their opinion was the stock 440 cam was just as good under certain circumstances).
Anyway, I currently have a low stall converter (~2100 rpms) and a 3.55 suregrip. If I swap in a Dynamic or PTC 3000 rpm converter would that wake the cam up or should I change the converter and cam together? If so, what cam?
This is a 100% street car.
I'd yank the cam and get something that will work with your combo. I didn't read all the posts but that cam along w/ the 509 is a race designed cam. It needs a lot of compression, good heads, headers, 3400 stall (or more) and at least 3.91's to be effective. I had a simial set-up in a 67 coronet when I bought it. The thing was a flat dog. I went w/ the summit 488 and it was 100% beeter for the application.
hahah thought this post looked fimilar..hey HyperSonic what's that car urun? It's a beautiful car...looks like a 10 flat car???? and nobody is saying a 484 won't run, but if you have a pretty much a stock stall and low gears there are better cams on the market.

I was reading what you were talking about in regards to cam's I have a 70 Charger with a 383 bb nothing real fancy about it at all. In fact I lost the cam for some reason and now will be doing some mild updates. I bought a Performer rpm manifold for it can you suggest a good cam ? This is a street car that gets driven around town and on the freeway.
Thank you
I never said I was faster...Just said your not getting in front of me....
