Hughes Whiplash cam testimony.

Quote:

---

Just installed, broke in, and test drove the 69 Cuda with a Hughes Whiplash cam in it. Motor is a 100% factory '70 340 motor right down to the cast iron exhaust manifolds. I was looking for a cam that not only ran better, but sounded much manlier. Kevin at Hughes Engines talked me into the Whiplash cam for the 340. The sound is somewhere between a 284 and a 292 purple cam (which is very healthy), but I'm holding between 8 and 10 inches of vacuum. With the stock cam, the car would spin about 3/4 the way through 1st gear with my peg leg 3:23s (about to be replaced), but now it will spin far into 2nd gear. The low end is amazing compared to before, but it pulls really hard to at least 5500. I don't have timeslips yet, but I can tell that it has the stock 340 cam beat all through the RPM range, and has a radical idle that turns heads. I hadn't heard much about the Whiplash before I bought mine, but I took and chance and I couldn't be happier with it. In the next few weeks, the car will get TTI headers/exhaust and a 3:91 sure grip, so it should pick up a good deal from that too. I will post video soon with sound before and after. Just thought I would share in case anyone else was considering a Whiplash.



P.S. Link on my signature is from the old cam, not the new Whiplash.

that might be a little uncalled for . the only problem i have with my hughes cam is keeping the front wheels down. how about a 5.91 1/8mi? it has over 116mph. yeah, bad cams

I guess "how cool it sounds" is something we all want, but this is the Race forum, isn't it? I don't know of any tracks that award wins based on how cool a car sounds, or how far it can "spin" (although this does sound alot like how they award wins for drifting , doesn't it?).??

With that admittedly flaming response said, I too am planning a Hughes cam in my next build.

The cam sounds "nasty" and makes the car shake or what not because it has a narrow LSA of 106. Used to be how the old race stuff was, very narrow. Now many aftermarket manufacturers are going to wider LSA's of 110 or 112.

I'd rather have people think my car is slow, and prove them wrong, than for my car to sound radical, but have little to back it up.

I am skeptical also

I dont get how it idles like a funny car and drive like a good street bruzer

is it just the high lift and short dur that duz this,of course I dont know how the # work on any of them...how is it better than the voodoo series cams

Sound is one thing I'm looking for I'm upgrading to stealth heads and an eddy 2x4 setup on my street 440 d100. I don't want to do an engine rebuild so the 106 centerline cam seems like a great idea to me.

I had a custom comp cams grind done for the last 340 I freshened. It was low comp 73 narrowed up the centerline to get some more cly pressure.

glad those whiplash cams are out there now!

At the official Mooseland dragstrip we give out a prize for distance!

And with the low manifold vaccum it will cause hell if you have power brakes!

Lowest ET. Highest vacuum. Smoothest idle. In that order!

if you had trouble with a Hughes cam you either got a bad one or did something wrong. We cant kill them and make big power with them.

Used to be...

Well... its not quite Speedtalk... but i'm thinking ov getting one ov these cams for my hotrod... which i fully intend on racing, and often. Does that count...???

Dont think i'm getting my question answered anyways.

---

Ov course it does.
As far as the question you asked that no one gave on the 8.5 ratio My guess is larger CC heads?
I know that in the years i have played with 340's some had taller deck hights and I have a set of J heads that are 74cc's those 2 alone would bump you way down in compression.
As I said I is a guess on my part that the OP had his piston way down as far as deck hight and not the .020 above like a perfect blue printed block would be and the CC of the heads were large as some run...........

Gonna resurrect this old thread because i'd like this answered. Would big block be different?

Question for anyone who has installed the whiplash cam in a low compression 340 (mine is a 73), are there any problems with clearance with the stock valve guides or did you have to have them machined down?
How about piston to valve clearance?

---

Also, OA5599, when those Whiplash videos were taken, did you have any head work done? Or is that a stock top end with the RPM intake?

Also, you say 8.5:1 CR with your combo, yet its a 70 340...??? I know the factory ratings were optimistic, but down 2 whole points...???


Just trying to get an idea ov what i'll get from this cam in a stock 67 383.

---

Sorry it took a few days to answer. But the low down on my old 70 short block is that it was rebuilt by the previous owner back in the 90s with low octane in mind as opposed to time slips. There were no clearance issues when it was installed, and the recommended Hughes springs and lifers were used with it. We drove it for 2 trouble free years with the Whiplash, and were very pleased. At the time of the videos, and the whole time the cam was in it, the heads had not been touched. Best 1/8 mile was 8.17 and best 1/4 was 12.96 at 104.2. Terrific street manners and plenty of vacuum. The only reason it was changed earlier this year was due to our dream stroker being installed. If we ever get another mild street car, it will be getting a Whiplash, too. If you have any more questions, let me know.
