Re: mopar smallblock .474 cam - 11/06/09 02:58 AM
I can't tell you mileage, etc, but I can tell you I really like the cam. It pulls well from idle to 6500. It builds lots of torque in my 340. I haven't wound my current motor past 5000, but I had this cam in a 340 years ago and it was great to 6500.

Yeah: I know a few guys that ran them decades ago and they worked great. Choppy idle but they pulled good up to at least 6000RPM.

I ran one in a stock 340 Dart with that cam and it had headers along with an Eddy dual plane intake that looked like an aluminum stock intake and a 650 DP. It was a 318 car and I dropped this 340 in for my girlfriend as it was her car. Left the stock 904 and converter from the 318 eng in the car. It drove real nice and had great low end. And it pulled nice up top for what it was. I ran 13.49 @ 105 on street tires and I mean street tires from 1980 as it would not hook at all. I feel sure with the 105 mph it would have run 12's with slicks and that was capped up. I liked the cam alot. Ron

here is when I get some questions. For same cam I got divided opinions to a 400, taking in mind I will raise compression with pistons, but then it looks good mounted on a SB, with less displacement and stroke, and no more engine build specs posted
I simply don't get it.

I ran that cam in a couple of 340's back in the day. 340 4spd 'cuda, pulled the revs to 6500 and 12's through the lights. Lot's of chop at idle. Loved that hemigrind.
Ran one in a 340 in a 4x4 W150 in the mid '80s, all the usual mods (LD340 Headers, 440AVS, good X heads etc) , was faster than the basically stock 440 (HP manifolds, TRW's, Torker, 750 Holley, factory HP cam) that came after the 340 broke the steel crank. Strong midrange torque in the truck, choppy idle, low vacuum. It was a mean cam.

I run it in my 360 -
stock long block with an eddy street ram and 2 holley 390's on top - 3.23 gears and 26" tall tires
I get 14-16 mpg on the highway - 3400 rpm @ 75
I run 1.74 60'
12.56 was my best et
108 was my best Mph
I pull 9-11" HG at idle in gear / out of gear
I like it.

I still run that cam in my 340. Got nothing bad to say about it. I run about 18 degrees of inital timing and it has great manners for the street.Sounds great at idle. Have no idea about milage. I drove my 340 all over the west this past summer with that cam including to the top of Pikes Peak and in the desert heat of Reno Nv. Car ran great everywhere. I've had this same cam now in three different motors, it's out lasted the motors.

This is great feed back on that cam,I am planning on pulling my comp cam out soon and that is the cam i was thinking of.I can get it here at my local Mopar dealer for 198 bucks includs lifters.One Question did any of you have to change to different pushrods or go with adjustable rockers I want to double check because so many of you have run this cam.So can it be installed useing stock pushrods and stock rockers.Thanks Dons Dart.

now the feedback seems to indicate this is a very good street grind for a warm '340!
........tx a bunch guys.
are we looking at 15 degrees initial with about 9:1 comp?
i have welded the slots in another distributor to reduce mechanical to about 20 degrees.

Re: mopar smallblock .474 cam - 11/07/09 12:57 AM
..you're not going to believe this but i found the paperwork for that build(2004) and that is the cam we used not the .484
i remember the Dart running very strong initially and when i changed to the 3.23's and started fouling plugs i couldn't get it to run right.
as you know i spent all my time on that Duster for the last 3 years,and now that it's finished am back to the Dart.
with these responses it's definately not the cam but the engine tuner...oops did i say that out loud?
oh yah....stock rockers and pushrods with the .474..........al

Re: mopar smallblock .474 cam - 11/07/09 02:40 AM
I use stock arms and pushrods also. One thing I seem to remember about my first go around with this cam is that I believe it "builds" compression due to the timing of the valve events. I think it would be excellent for a true 9 to 1 motor.

I'm running the Purple Stripe .474/.471, 280 duration,....340/6 4spd 3.91 gears,...the motors dynoed 443 HP usual goodies in the rebuild, 11 to 1 compression revs freely to 6500, but I try to keep it under 6000,....this cam/engine combo comes on strong around 3000 RPM on up,...not bad idle, rather choppy, I idle around 1200 RPM, but it sounds more like 600RPM, it that lopey 
I run a Mallory YL dual point reverse rotation Marine distributor with mechanical advance that holds the advance plate stationary until approx 2000 RPM, the advance plate is keyed for 28 degrees all in by 2000-2500 RPM, I run 10 BTDC initial, this set up gives the motor a good launch off the line, really puts the power down fast

Re: mopar smallblock .474 cam - 11/08/09 02:00 AM
Great cam! My 72 Demon ran 11.80 at 115 with this cam. Engine was basically a stock 71 340 with stock intake, TQ carb, steel crank, kb pistons, unported heads, with a 904 trans/stock OEM 318 convertor and 4.30 gears. Tire was a 27" slick with TTI headers and full exhaust. Sorry I changed the combination....will probably change back. Cam was a .474 hydraulic with with only .030 travel in lifter with adjustable rockers.

Re: mopar smallblock .474 cam - 11/08/09 02:20 AM
I agree that cam has to do something with adding compression, air elasticity and all that. I tuned a six-pak '73 Dart Sport 340 for a friend that bought it, and supposedly was a "built" engine. The car would beat my 440 'Cuda and a lot of others. It was real loud though, had headers and those see-through mufflers. The point: after we tore it down...8.5:1 compression - bone stock, 360 heads, 3.23 posi, and a shift kit! It had 9 or 10" at idle and timed at 12BTC, but that was on 1980's gasoline. The friend still wants the same combo to this day...for his kids. That cam rocks a smallblock.

Do they make the same cam for a '98 360 roller block? If I had to, I could go with a earlier timing cover and use the longer cam with the fuel pump excentric, but want to keep the roller, in the setup. This cam sounds like exactly what I want/need. Any part numbers for it?

..Steve..you have some experience with the comp XE268.How do they compare?
I'm thinking with a gear the .474 might E.T. better and the 268 would help a low compression engine and have better bottom end.
What's the least gear you would expect the .474 to like with a 4 speed,3.55?..my 3.23's are shot?

Re: mopar smallblock .474 cam - 11/09/09 02:18 AM
try a 3.73-3.91 gear with the .474 cam
In the 4 dr I'm running the 323" with a MP2783 .430/.444" 340hp cam, and have smashing results with a 3.23 gear and 4 speed manual.
2783 Runs out to 5000rpm or so. The .474 will like 5,500rpm + with a 3.73 type gear.
I felt a large cruising difference from a 3.23 to a 3.73 with 25.5" tires...
For me, every engine with Hyraulic lifters and pushrods has always ran out around 5,500-6,000. A solid lifter valvetrain has to take charge, from there, give or take.

you could run the flat tappet in the roller block. personally I'd either regrind the roller cam, or pick up something like a comp XE268HR.
pick up a used roller cam out of an 80's 318, send it to bullet cams, and see if they can put their HR280/320 or HR274/325 lobe intake and exhaust on it....

right now i'm at 12/35 and i know it wants a bit more brcause it wants to flood a bit occasionaly,so probably needs a little more time to burn.
my engine has decent forged slugs an probably about 9.2 comp.
i am running a 727 but hope to go to a 4 speed over the winter.
tx all,this has been great.

Well, let me tell you exactly how they compare. The XE268 has a modest lope and decent vacuume for the street. The Hemigrind has a chop that has a meaner sound but less vacuume. As far as peak power and rpm, they are pretty close; this would make a good dyno test but I would guess they are within a few HP. Both are very good street cams and will pull strong to 6000+ in a 340.

I have noticed a serious downward slide of the quality of our gasoline which you may or may not have to deal with "up there"...you using pump gas? If so, it just don't wanna burn! My last van - 360/TQ/'79 case in point. Took a carb from my 440, it was not rich enough. Jetted it once and even had to go to smaller rods after that, it finally ran after 3 changes. Only explanation= it's about 80% actual fuel and the rest is some recipie if you ask me. No way that carb was too lean for a stock 360.
