Any one have personal experience with the hughes B Block cams? I have an approx 8.0-1 400 with stock 906 heads or ported smogger heads with perf rpm manifold, 750dp holley, heddman street headers (1 3/4?) to go in a 4spd 70 rr w/ 4.30 gears, weight 3600. I'm considering the 3038 cam or 2330. Currently in the car is an 8.5 383 with the ported smog heads, rpm manifold and mp509 cam. Thoughts anyone?

I've got a 3038 in a mild 440 and it works great, Lots of midrange power.

i run the 2330 in a 9:1 440. i'd lean towards the 2330 with that low of compression.

I use one of their hydraulics in this 440+6 Charger and off the trailer at the end of the season it went 13.40's at 108. I hope for twelves this spring.

I have a 3030 in my 9:1 383, and the cranking compression is only 130psi, really low. I would suggestthat with the low compression to go with the 2330.
But, if you don't have the bottom end done yet, spend the time and $$ to get the pistons to come up to 0.00 deck, that should give you 9.7-10.2 or so compression, and then you can run the 3038.
The issue here is bottom end. Without the compression, the low end is really soft until about 3000 rpm. The gears will help, but just a patch. I think the 4spd and gears and rpm manifold willhelp, but you will be more happy with the 2330 on the street because of the fatter torque curve

Do somthing to get more comp, even with a 4sp you'll notice the low end grunt. I think you'll be happier with the 3038, If you get near 10-1 go with the 3844, its still should idle better than the MP509, but it will pull harder low and in the high RPM's as well. Those stock stroke B engines will really rap if you build them right.
I'm running there solid HV5663BS and its more mellow than I thought it would be.

My guess is that you have around 150 - 160 psi of cylinder pressure. With a low compression motor you should have those valves open and close asap to retain as much cylinder pressure as possible. I would use the HE2330.

Im runnin a 2330 in a stock 383, 10-1 comp with ported/drilled out exhaust 516s, stock converter, performer intake, and a still trying to dail in a e-bog 750cfm,3:23 rear.
With the 4:30 gears your running, you should be ok with a 3038, i personally love the 2330 Im running now, and would get another one in a heartbeat. Good Luck

I'm running the 2330 in my '71 400 motor that's in a '73 Cuda. Stall is 2800 with
3.55 rear and 727 with shift kit. Heads are
346's with a Stage 1 port flowing at 250cfm
at .500 lift. Rockers are Hughes 1.6 rollers which give me a lift of .538I/.549E. Heads have been milled .050
to give a CR of about 9.5. Intake is a Weiand Team G single plane with a 750 Holley DP. Headers are Hooker Super comp.
1 7/8. I am really happy with the Hughes top
end stuff - motor ramps up fast - starts to really pull at 3000 and in a blink you're at 6000. No complaints!

Hi
Sorry to ask that too but I am having a hard time to decide if I should keep my 284 MP purple cam in my 440 (on the purple cam thread) since it's supposed to have bad vacuum and won't pull below 3000RPM!
I was looking at the hughes cams. I also saw the HE2330BL and the HE3038BL before reading that here.
It's a 72 RR with a 440, lightly ported stock heads (what heads are those?), will have 17/8" TTI headers with 3" TTI, 750 Holley, stock intake, ECU and might get the Diamond flattop 10.5 CR pistons they offer right now. Now I also have flattop with about 10.5-11CR. No idea about the dynamic compression! Live at about 2000feets altitude.
Want also to put the stock converter in that car. (2200?)
A few things I want: emission max. 4% CO, not to rough idle and enough vacuum to brake that car in an emergency! But want good power (300 RWHP would be nice if possible?) and good reliability on that cam.
Is the HE2330BL or the HE3038BL the better choice? What do you guys think?

I had good luck with both the 3844 hydraulic and 4550 solid.. The 2330 would be a good choice for your application..

I just saw that there is a minimum PSI for each cam. The 3038 wants 160PSI what are 11 bars (11:1) so my about 10:5 engine with the stock iron heads has probably not enough SCR! The 2330 requires 150PSI what are 10.3 bar (10.3:1) . I also think that one is the better choise, the 3038 might be to radical.
Now is just the question of how much power this 2330 makes and if the CO emission will be worst than 4%...

I ran a HEV5056 in my 440 along with Hughes Stage 2 906 heads....car went 10.93 @ 122.
It was 11 to 1 and on the street I ran pump gas with the timing backed off about 5 degrees. At the strip I ran 110.

6040 - I think Hughes cylinder pressure requirements are a tick high. His cams make BIG cylinder pressure!!! So comparing what you have now to what you may have with his cam is difficult. If you have 10.5 I would run somewhere in the 250-255 @ .050 duration cam. Just my 2 cents....

71Cuda - In the 250-255 @ .050 duration?? That would be a HE4854BL!? That cam sounds like for a 500HP engine?!
I really want good vacuum for my PB and don't forget the 4% CO emission (although don't know how much I can get down with the emission by rejetting the carb and playing wit the CO screws).
Or did I understand you wrong?

I'm with 71Cuda and Tim, I run the 5056 solid cam. Mine is in a small block though. I run 11.6 and should run 11.3 next year with a few changes. Still pump gas, full exhaust, driven to the track.
180 psi cranking compression with 10.65 to one motor.
Great cams!

I'm not up on the emission regs. and stuff so you would have to do your homework there.........
I'm saying ....if your comp. is actually 10.5 then you "could" run a bigger cam....BUT you have to keep all your needs/requirements in mind.
I always give my opinion on max HP.

71Cuda - Ok, thnx I want power but with 3.5$/gallon and driving maybe for 1-2 hours at 90mph on the freeway and also city driving I think that cam is way to big.
Darn, just saw the prices for the lifters, rockers and all that, gives a nice sum at the end!!
The hydraulic rollers seem to have their RPM range at much lower opening times! Is that because of the really fast rate opening of the valves? How are the experiences with those ones? (besides the high price...)

I bet nobody here has swapped their 509 cam for either one of the 2 you listed. If they did I would love to know the et difference between them. That 509 cam is tough to beat with anything close to its same specs. If I was bent on changing it I'd choose the bigger one. My .02 cents, Rat.

I run a Hughes 3038 in my 340 powered '71 Cuda. 4.10 gears and a 4 speed. Motor is 10.5:1 and doesn't ping on the local 92. Runs smoother with some 115 mixed in though. I love the cam. Motor sounds tough and pulls hard above 2200 or so all the way to 6000 (rev limiter set at 6k). Another guy in the club is getting a 1423 for his milk-mild 383 68RR. He currently has the MP509 (way overcammed). Funny thing...around here folks are real reluctant to get away from the vaunted MP509 but everyone that has gone to a new design, high lift cam runs faster and loves it. There is still that "I got the 509" thing though...almost like braggin' rights. I find it silly given the dulcich dyno proven results the newer cam designs, coupled with the right combo can provide (not saying 509 is bad, just newer designs are better).

I am tossing around the idea of either the 3038 hyd, or a mechanical 3945. I am going to throw it in a 10.5 360 with a set of Stage II heads. I cant decide! Probably the 3038??

Guys, about the hughes 2330 and 3038, what MP cams are these close to? yes, i know they are probably dual pattern and better, but all i know are MP cams, so if anyone can tell me the MP cams that these 2 hughes cams would be close to, that would help me out, i am running the MP 284/484 now, i am assuming the 3038 is a little more cam than the 284/484 and the 2330 is more like the restoration RR cam, or am i way off?

The 3038 cam is similar to the 284/.484 but has a little less duration and a bunch more lift and less overlap. If your heads are ported, I would go with the 3038. Dont forget to have headers, intake and enough compresion.
I run stage 5 iron heads with about 80 cc chambers figuring 10.3 compression. I got rid of the 284/484 cam and put the 3038 in last year. Its a great cam. At 4050 lbs and 3.54s and no traction, I have run 12.7 at 109. This is with a slow 2.15 60 foot time. The winter project is traction action...and I cannot wait till spring.

Mr 71 Bee - So that 3038 cam would be a good replacement for my 284/0.484 MP cam huh?!
Compression will be 10.5-11:1 on my 1972 RR 440-Auto. Will have some head (stock) porting and got the 17/8" TTI's, stock intake and 750 Holley with 3.23 SG gears.
I want more vacuum so this 3038 little less duration and a bunch more lift and less overlap it should make more vacuum with better power right?

6040.......my bee idles at about 900 in gear with 13 to 14 inches of vacuum. Its got a nice lope to it. In my opinion, with your compression, you could maybe go with the next size cam......BUT, the rear gear would hurt you. Give the boys at Hughes a call for a recommendation...

Wow I like the power range on the 2330 and the lsa of 112. I wonder if this would work well with a 383 with 150 psi compression chech 750 DP 3.55 and a 3000 converter? Mid to low 13's?(through HP manifolds) mabey.

Mr 71 Bee - You got a 440 in that bee with this stage 5 iron heads? Your vacuum sounds very good to me! I think I will stick with this 3038 or the next size. But you are right, the guys at Hughes surely can help me too to decide that!
If Isky had some hydraulic "Chrysler-cam" I would like to try one of them, but they just have the solid like that, although hyd. are coming...

I am running a 383 with 72cc chamber heads, Hughes 2330 cam, 3.55 gear, 2400RPM stall, 1&7/8" headers, 2.5 duals with an Hpipe, 750DP Old ass Torker 383 intake.
I have exactly 150psi cranking pressure, BUT!!! for some reason I get about 16" of vacuum at idle? Any ideas as to why my vacuum would be higher then what everyone else gets with the same cam?
I have yet to run the car at the track. It feels like I have a 3500RPM stall in it, Traction is no where to be found. Any ideas?
About the post. If you are running power brakes in your car, I would get the 2330. Moparlulu has both the .509, and the 3038 in both of his Chargers. He might chime in with some advice on the two!

Redmist - Why are you worried about this high vacuum? Is it bad to have so much?
Traction is no where to be found? Sounds like you got a torque monster with this cam?
The MP cam 284 is very bad on vacuum what I heard. I think the 0.509 has to be worst?
Yeah, would be good to know how the vacuum is on the 3038 or even one step higher!
