Help picking a cam

Help picking a cam - 02/13/11 05:05 AM

Need some help picking a cam for a low budget build.

.040 over 440, Keith Black pistons, 6 pack rods. 10 to 1 compression. Street Dominator Intake, 800 Holley Double Pumper, 346 heads that are stock except being freshened. 2 inch headers. Car should weigh around 3800 lbs. I have a 9.5 inch converter that should flash close to 4 thousand RPMs. 3.55 or 4.10 gear.

Im figuring the headers are probably a little big, but that is all I have at the moment.

Due to a shortage of funds, Im stuck with an off the shelf grind. Looking for recommendations for both a solid and a hydraulic.

If anybody has built a similar motor, ET, MPH and cam used would be great also!!!



BTW, Im not interested in the VooDoo grinds, anything else is fine. Long story.

525 comp XE grind loks pretty good for your combo. , that being said i went with the 564 lift xe grind for the 440 in my A100.

I went with an old skool MP528 mechanical. WOW what a great cam. Daily driveable, medium lope, fries the 295/60-15 BFG drag radials thru 3.55 gears. 470". See info in my profile.

I run a voodoo cam, no problems. I would have suggested a voodoo 60304 would fit the bill nicely.

Since you said budget build, i'm guessing you may be using the stock rockers. If so, i've had good luck with the old Comp 292 Magnum hyd. .030 440 8.5 comp, 906s pocket ported when i was 20yo and didn't know what i was doing(still don't), Torker,750dp, 10 in GER stalled about 3800, 3.23s, 28 x9 slicks, 68 Satellite street car all steel except for 6 pak hood. 12.35 at 106, 1.69 60 ft. Cam has been in for about 25 years and hasn't gone flat yet in spite of me not always changing the oil as often as i should. Car sometimes sits for months and then might be driven almost every day for a while.

Guy here selling an engle 230-238 @ .050 would be A GREAT CAM for you.
Headers are too big but 4.10's will help the loss of bottom end/midrange(especially on part throttle)if you care.

Ive actually got some 1.6 rockers.

What RPM do you shift that cam?

Thanks

There are way better cams now then the old cc292. A buddy of mine built a very similar deal last year, had an old comp 280 (230@50) and went to the comp 284xe and gained around a half second. This was in a fully stock body '68 Bee, ended up going 11.6X .

I have had good luck with the.528 mp solid too, but there are better grinds now worth investigating.

Not sure on "way better" part......I laugh everytime a new grind is the shiznit, and the old stuff is junk. My junk runs decent (11.30s)with pretty old lobes (Comp TL lobes).....Thinkin about having Dwayne grind me a cam with the super duper new stuff for a comparison.

Well lets see... the XE284 grind has 10 more degrees on the intake side than the 280, 16 more on the exhaust..., not to mention the extra .25 ish more of lift. The XE grind has 13 more degrees at .200 than the 280. So yeah, it should be quicker. I dont think that is a good comparison.

The XE274 would be a better comparison. 3 degrees more at .200 than the 280. Same intake duration at .050.

The XE284 and 292Mag would be a much better comparison, for the larger grinds. I'll throw it out that in a heavy car the 292 takes the XE284......

Im not a fan of split duration cams, and after talking at length with Dwayne, I understand why.

All I was trying to get at is don't buy a sh!++% old cam. I subscribe to the theory that there is no such thing as too big of a cam/conv/gear. Of course this is the wrong forum for that, but I must explain where I come from.

I agree on the cam/conv/gear thing, but not that the 292 is a sh$$$ old cam. Ive known forphorty for a long time and his stuff runs hard...with hardly anything. Ask the all knowers if his stuff should run 12.30s with... gasp....3.23s...

Anything is possible. In this case, WEIGHT is the
big factor. Bunch of mass to move (a little over two tons w/ driver) and the low end/strong midrange level cams would get the job done. Higher lifts (.500 or better) would only help MORE.

The only reason I would disagree with that is there are better cams now. The lift on that is .501(?)...And with the bending and deflection of stuff, its under 500 lift.
Don't get me wrong, I've seen those cams work too.

A lot of guys optimize those MP cams to run better
times with the rest of the combo on the engine.
It's a hit or miss game, what could be the cam holding power back could actually be tuning problems, wrong intake, exhaust restrictions, too heavy car for combo, etc.
or visa-versa. EVERYTHING has to work together to produce good power!! And yes, not everybody wants to run an MP cam, there ARE many other choices.

Relax man! Just adding to the choices out there for cams. We all know that MP cams were not mentioned in the post. So, no harm done to the Comp Cams followers. Respectfully, they (CC's) are a good design also.

In SOME instance more lift to a point in relation to duration, equates to MORE TORQUE. Mopar BB heads flow pretty good for street/MILD strip usage
w/o "heavy" massaging. A MODERATE duration/higher lift cam is best for a hot streeter. Bigger (longer duration) cams want bigger port/valve heads. Not needed here!! The K.I.S.S. principle.

Here, I'm throwing it back at ya!!
The update (test page), works WELL for 3500-3600 pound B-bodies. The poster
has nearly TWO-TONS of car. The performance of those cams DO NOT relate to his CAR WEIGHT!! Look, I'm not knocking the newer cams, but you fail to realize that WEIGHT effects the perfomance. You can make horsepower, but torque is needed to move the MASS effectively. Want to run HARDER, lighten the car!! THEN, pack in the horsepower. BTW, the RACER BROWN cam
looked pretty good, probably the most driveable one of the bunch!

Re: Help picking a cam - 02/14/11 05:44 AM

Well his combo is almost identical to mine. I run a .030 over 440 with stock bottom end other then the KB quench pad pistons that give me quench with my open chamber 906 heads. Its 10.0 comp and I run the Holley Street Dominator intake with an 850 DP. I have Hedman 1-3/4 headers and use a Dynamic 9.5 converter that flashes about 4200 at the track. My 63 weighs just over 3700 with me in it and I use 4.30's with a 30 x 9 tire. I use the MP .557 cam and I have ductile iron 1.5 rockers. Suspension is all stock other then SS springs and 90/10 shocks up front. Best et is 11.49 @ 116 with 11.50's to 11.70's the norm is hot weather. I drive on the street way more then I race it as I only race 2 or 3 times a year but put alot of street miles on it. I like the .557 cam as it makes ok power and has great driveability on the street.

How do the cams NOT relate to car weight??? Look at the torque #s the RB cam put up.

I think you are not seeing my problem with some of the comments on this thread,and most other cam threads. To make the statement that "this cam, or that cam sucks, is out dated, is a SHi445 pos, etc", is totally ridicoulous.

As you said its all in the combination......I agree that most cam related problems are due to other issues, (compression, converter, advance curve, tuning, etc)

But, as in forphorty's case (whose car is no lighweight, 3600 and change I believe) if I asked 100 people what his car runs with no compression, 3.23s, very little headwork, and a high mileage motor to boot, most generally the answer would be "That cam is too big, it will be a flippin hound" or something along those lines.

Too many blanket statements thrown out on this board that are at best half true.

Could you at least post the whole article? I didn't see the part about the sub 500 lift cams.

Andy is a serious asset to the mopar community, I'm honoured to see he recommends the same hydraulic as I do

Glad we can finally agree and move forward.

Not so fast there, pundit. Looks like the old school crap RB cam took the honors.... Something to the lines that they could tell the shiznit Comp hyd didnt have the low end that the RB cam had and the dyno backed it up. Hmm, split duration had less torque than the POS old school RB, where have I heard that before?

I'm not going to dwell into Andys article as he would tell you ,which I'm sure you know, every combination is different.

Thats MY 470" shortblock in that article. I bought it off AndyF (Moparts member that DID the article). Actaully when I got it it HAD a CC cam in it. I pulled it and returned it (he dynos with Schubecks) and put in an MP528. Installed and broke it in one evening while also cooking dinner for the familiy after work. Just spagetti.

First of all Andy produced a GREAT article as always, very informative and detailed. Major props
to him!! Next is the issue about weight and power.
As a simple recap, I looked at the highest torque
producing cam that had driveability manners. Thats
why I look at car weights vs. cam lift/duration. All I'm saying is that the heavier the car, the
more torque has to be placed in the engine power range at lower side and midrange (2500-5000 rpm).
The car can horsepower up to 6000-6500 maybe, but it's the effective torque at the lower scale which MOVES the mass and the horsepower maintains the momentum.

That works well too with the same converter. 4:10's are the standard gear with it.

No, there are NO blanket statements here, just the human nature of each individual who HAS a certain combo on their thinking it's the best.
Not all MOPARS that rolled off the line are 100%
exactly alike!! They vary in weight, trim packages, body styles, engine/drivetrain, etc. So the thought of one cam fits several combos is seldom and for the combo to run alike is far and few, unless they are 100% "clones".
