cams

[Don Dulmage <big-d@xxxxxxxxxxxx>]

I have not seen a cam better although I did find one as powerful. but it was murder on springs which the Racer brown was not. 
It is faster than the mopar mini express 654 mushroom . Faster than the ultra dyne 613, faster than the comp 650  faster than the mp 509 and 590 both.  just for a few. 
Its biggest frawback is it was designed 40 od years ago and people just cannot concieve the idea that Racer was that far ahead but he was. He understood our engines like no other. 
I am talking now my style of motors with ported iron heads (280 to 290 cfm)   Once you go to the eddy and indys  you can run a lot more lift. Still though a good Racer B could give the competition fits. 
I believe one cam in particular the ST-h 42 has no peers. period.  it is just flat out violent. 
The extrme energy by Comp is the first real serious work since racer brown that has been done for our mopars. Before that we were just buying Chevy cams on Dodge cores whether we choose to believe it or not.  I have had some good success with Lunati cams too. Especially the Cheater Stocker series. Both hydraulic and solid lifter. They are harder to get now. since holley turned it from a technical company into a package and sell outfit but those cams are still around here and there. 
Me though in truth i am wearying of explaining what i found out.  Must be getting old. 
I constantly hear I bought this instead of the racer brown and I see for the chioce they did not understand. The racer costs no more, was fastrer and easier on parts.  For me that is a no brainer. 
Comp cams has  some chrysler specific lobes in thier library  which are good although lift is too high to be real good for iron heads but they wil mae them for you if you understand what to order. 
I guesss the bottom line is this. 
We ran 11.51 or I did  in a 3950 # car with me at the wheel who weighs 306 # . That is 4256#. That actual run is in the video or dvd  some of the folks have. (I broke out against the camaero coupe) The car had 4.57 gears. 10.5 slicks  and shifted at 6150 rpm. I personally have not seen anyone recently run that heavy a car wth those times. I am sure someone is but not in my area. Why would a person not want that type of performance when it is so straight forward and simple.? Because i think it is so straight forward and simple. Not shiny enuogh , not fancy enough just real darn fast and trouble free. cant possibly be is what the "ezperts say, but it is.  Racers cams both were a big part of this success. I tried several others in that car. They just didnt have the suds, desite all the hype i read about them in Magazines and ads. What more can i say? 
Take a similar grind from someone else and takean ST H 42 for instance and set them side by side. The difference will floor you! You will suddenly realize there is a lot more to mopar cam desgn that just siimlar specs on a sheet of paper. How fast it opens and closes is pretty significant. Racer already understood these limits  and took full advantage of them years before anyone else.
If you have a distain for old technology and some do. Then search "Bombardier Beetle" and see how old the rocket engine really is.  Yeah I think the RBs are superior in many cases. Far better than we realize. Sure they can and will be improved on but it wont be by MP  anymore than the chevy guys are expecting the next big cam to come from GM perfomance parts. It will be from some little guy shop who is playng around to see what happens when he tries this or that.  Not some big firm run by a money hungry blood sucking parisite (aka BSPs) who only can see how many they can make and sell. 
WHen i did the Lemans Pracice engine (400 Mopar ) for Europe, I asked Christphe Schwartz why he came to me for the motor. He said in France where he lives they have a saying.  "All the best cakes come from the smaller shops" I had never heard that before but to me it made sense. They have the time and interest to make it as good as poosible and dont needto sell 0000 every day tostay alive. 
Sorry I got so wound folks. I AM awake now!
