I am going to change my cam and would like some opinions please. I want to stay hydraulic and the car is street/strip so its gotta idle.

Currently: 66 .030 440 with Crane 230 duration .480 lift. TRW 2355 six pack forged pistons, edelbrock 84cc 2.14 1.81 heads, street dominator with QT pro 850, headers. FBO ignition, 727 with TA 3300-3500 converter with 3.91 gears 27" tire.

My car runs 12.3, I want it to run 11.5 and I think I could benefit with a better cam. I know its hard to tell without PV numbers, but I am looking for idea about what name or brand. An idea whats to radical, like a .750 lift and too lame.

Thanks.

Thanks.

What kind of car? Weight?

mopar solid 557 w/ 1.5 rollers should do it.

You are asking a lot for a cam change, roughly 100 hp. Ain't gonna happen without some serious changes. Can you reduce car weight? Consider a hydraulic roller cam? Head work?
If you really want to stay hydraulic and gain that much power, you will need to extend the rev range(roller) or stroke it to get the airflow at lower revs to make that much power. There are sure to be guys on hear that will chime in with combos they have built that may meet your goals.

ok,
you have a 67 Dodge,maybe 37-3800lbs?
you can do it.
i have a 68 satellite,approx 3700lbs with driver,runs 11.41@118.5.
440 +0.055,10.78 comp,m1 single plane,825 mighty demon,prepped stealth heads
i have a purple 509 cam,idles in gear at 750/800 rpm.the downside to this is i have to run a vacuum pump for the brakes,there is a revised version of this cam-wider lobe seperation will pull better vacuum.Comp etc all do similar cams,i also like their XE/XEHL cams check piston valve clearance.
exhaust must be right.i have 1 7/8 hooker comps into 3",aero chambers and finish at diff.
i also have lighter,SRP, pistons with a performance balance.
get your suspension right,i have qa1's front ,rancho rear shocks.clamped rear mopar xhd springs no caltracs no snubber,small block tbars.
i shift at 5900 and trap at 6/6100.this is with a 28" et street radial,3.91 gears and 3200 stall converter.
yes it should run quicker with more converter/gear
Good luck

I dont see just a cam change picking up 8 tenths. But that said your combo is very close to mine. I have a .030 over 440 with 10.0 comp using 906 heads I ported. I also use the Holley Street Dominator with an 850 DP. I use the MP .557 solid cam with Isky ductile iron rockers. And I run 4.30's with a 30" tire. My converter flashes about 4200 at the track and seems to work good with a best 60 ever of 1.58 and a best et of 11.52 @ 116. A nice solid cam will help alot but I think you will need more changes then just a cam to go from 12.30's to 11.50's. Good luck , Ron

Were the heads gone thru before you bolted them on?

What kind of car do you have? I have a question for you. How do you like your turbo action converter? i am getting ready to order one fore my 440 73 dodge dart.I have a engine combo pretty close to what you have except I have stock size valve, home ported 906 heads and 1.6 roller rockers. I am running 4.10 gears and 275/60/15 M/T street radials. my intake is a mopar m1 tunnelram with 2 carter 750 carbs.I am using a comp cams 305-525 hydraulic cam. In my car it ran circles around my mopar 292-509 cam. I made my frist pass with it in my 73 dart last weekend. but i have a converter that is stalling over 5200 right now. so i think there might be some more in it. here is my fastest pass of the night.

60 ft- 1.6483
330- 4.8464
1/8 et- 7.5760
1/8 mp- 90.05
1000 et-9.9467
1000 mph-102.02
1/4 et-11.8555
1/4 mph-110.02

this same engine in my old 65 plymouth with a no name 3500 stall i have dipped into the 11.70 at 113 mph. Now i dont know if your car will run the same as mine but our car combos sound real close to being the same. best of luck to you on your goal. Mopar65

wow ron my car sounds like a slug compared to yours.my engine i just used parts i had laying around. it is a stock bore 73 block, junk home ported heads and a set of 440 six pack pistons out of a 70 440 cuda. ron how does your car drive on the street with the 4200 stall converter?i will be getting a 3800 stall turboaction for mine and thinking about getting the mopar 296-557 solid cam for mine. Thanks Mopar65

I like my 4200 stall behind my stealth headed 505,70 RR

hey sounds like a nice car you have there. how far do you live from fort wood mo? have you raced your car and how fast is it? thanks Mopar65

Hi Bobby! Like Ron,I REALLY like my 9.5" Dynamic! When I put in the new cam last spring,the flash stall jumped from 4200 to 4600! And on the street,very docile! You'd never guess it was that high of a stall when driving normal,which isn't very often! As far as cams go,I recommend an SQ lobe Comp solid. Really woke up my .040 over 440! RandyB

Havent had it to track yet planning on going to the nostalgias in september at kcir Im between columbia and jeff

Comp cams 308 street roller would work really well in that combination

My combo is also a 440 .30 over with 2355 slugs. I run a Hughes 572/579 solid with 272/279 @50 cam. I have indy ez's stck port heads with a eddy victor int. 3.91 gears with 28 M/T street radials. This cam idles nice with a pretty fast chop. I also run power brakes with this cam (couldnt believe it) All my susp is stock and I still managed a 11.49 @117mph with a 1.66 60ft.so far. Im sure theres more in it. I need to do some susp wrk. I did run a comp XE295hl (hyd flt cam)cam and it ran pretty well also with a mean idle. It just died after bout 5500 rpm so i went solid. Oh yea my stall is a 10'TCI 3500-3800 stall.

Hey! Correction on duration of hughes cam 252/256 @50. Sorry bout that, ive had so many cams i forget all the specs. The clearance was pretty close but it cleared. Of course 'i ran the cam with straight up with no advance nor retard. I cant remember the exact clearance but I remember having plenty of clearance on the int. side but it was close on the exh side. I want to say I had bout .020 to play with on int and only bout .008 on exh. to play with (not much). But so far i've had no issues and its gets reved to 6500 often. FYI its a hughes HTL5256 cam (one bolt)
