So I was playing with DD2000, and while I know I shouldn't put much faith in it, I just can't believe what its telling me.

Example, here is what my car is about right now:

Here

Now everything the same, except changing cam data from the 304 to the 503:

503

It seems to get it right, but there's nearly no difference!

So either I'm doing something wrong, or this program is crap. Or there really isn't a big difference, though I think there should be. So what do you guys think?

if there were places to plug in duration @ .050 and .200 as well, you would see more of a difference in the program like you will see in real life.

adv dur - .050 - - .200 - - lift w/1.6

CC 304
266/276 210/220 127/137 .533/.544

CC 503
276/281 224/230 145/151 .536/.544

The CC 503 is 14/10 larger at .050 and 18/14 larger at .200. and should be 15 HP/TQ better than the 304 cam with a lil choppier idle and have the entire RPM band shifted up about 300 RPM.

Just lots of variables that you can't plug into that program to see "real life" differences. If comparing cams that have comparable ramp speeds you should be able to compare the "difference" in the HP and TQ curves (gain X HP/TQ at this RPM, lose X HP/TQ and that RPM, etc) but the actual HP #'s can still be scewed due to the other variables in cam design as well as variables in every other thing you can plug into the program.

Ah, that's why your website hasn't been working. You moved!

I've been wondering what the specs are on your LE1/LE2 cams, and if you sell them separate from the heads or not.

Also, what kind of compression do your LE1/LE2 heads/cam packages run? Thanks!

My, changing it to .05 lift really changes everything! I can't believe how different they are.

$300 for the custom billet cams. Herea re the ones I will have listed on my web site. All of these are compatable with LE1 heads and the Crane springs and retainers I use. If using Patriot Gold Extreme springs or PAC 1220 bee hives, we can do some more aggressive stuff.

218/224 .544/.544 111 LSA. - 1500-6000 RPM
Great low and mid range power with very mild idle and will easily pass emissions. Works with stock gears and factory converter. Comparable to popular Crane 227 cam and GM 845 cam.

224/230 .560/.565 112 LSA. - 1700-6100 RPM
Largest emissions friendly cam. Pretty mild idle and still able to work with stock gears and factory converter in F or Y body. Needs small stall and gears for B body. Comparable to GM Hot Cam and Crane 846 cam.

228/235 .560/.560 110 LSA. - 1900-6200 RPM
NON-EMISSIONS version of 224/230 cam mentioned above. Mild to choppy idle. Good HP/TQ through out and a very usable power band. Best choice for "most people" using stock bottom end. Minimum 2800 stall and 3.42 gears for B body. Comparable to Comp 467 XFI cam.

232/240 .584/.584 109 LSA - 2200-6400 RPM
Choppy idle. Good mid range and top end power. Minimum 2800 stall and 3.42 gears for F and Y body. Minimum 3200 stall and 4.11 gears for B body. Comparable to Comp 306 cam.

237/246 .584/.584 108 LSA - 2400-6600 RPM
Very choppy idle. Good mid range and great top end power. We suggest a "built" bottom end is to handle this RPM. Minimum 3000 stall and 3.73 gears for F and Y body. More gear and stall will be even better. Comparable to GM 847 or Comp 468 XFI cam.

These cams are designed for popular combinations using stock bottom end LT1 or 355 engines and will work for most peoples set ups. A customer with a 383/396, solid roller, turbo, supercharger, extra wild, extra mild, etc, etc, will want a custom cam designed for there set up. We can design one at no extra charge.

There is not 1 camshaft that will fit the needs of everyone so we have designed several camshafts for popular set ups that will fit the bill for about 80% of the customers.

Just give us a call (972-617-5671) and we can go over your set up and help you decide what cam will work best for your set up.
