How Accurate is Camquest?

If you can't see it here it is.

Just found a way to enter custom cam info if you're using this program.

First, build your engine in Camquest, and find some comp cams # that comes up as a possibility for your motor. Write the # down, example 21-225-4. Pick a comp cam that you don't intend to actually use (or want to compare against), since you're going to change its specs. Save your engine and exit Camquest (you can stay in, but you'll have to exit and open again to see your new cam).

1. Find the shortcut to open the program; right click on it and choose "properties"
2. Click on "Find Target"
3. Go into "Manuals & Videos" folder
4. Go into "Menus" folder
(you may want to make a backup copy of CompCamsData6.txt now in case something goes wrong. Press CTRL-C, then CTRL-V to make a copy).
5. Click on "CompCamsData6.txt" to open it with notepad or another text editor.
6. Press Ctrl and F to open the find dialog.
7. Enter the # you wrote down 21-225-4 and press enter.

You will now see something that looks like this:

Chrysler 383-440 C.I. 8 CYL. 1959-1980 "Hydraulic-Street / Strip, needs 2800+ stall 9:1 comp, rough idle." Yes Yes Yes Yes

Xtreme Energy™ Hydraulic Flat Tappet Camshafts Hydraulic Lifter Hyd. Hyd. 2300 to 6500 21-225-4(Single Bolt)

XE284H 284 296 240 246 0.507 0.51 110 106.0 K21-225-4 SK21-225-4 [7] CL21-225-4 [7 ] Not Applicable 822-16 [61]/867-16

[37] 2104/3104 1321-16 [23]/1071-KIT [23] pg. 278-279 911-16/925-16 [2] 741-16 627-16 [27] 505-16 [2]




Now you can change the values in bold. First thing is change the model (XE284H) to the name of your cam (e.g. Isky292 in my case) so that you can spot it easier in the cam quest program. You could also change the description if you want.

Now change the rest of the values to match your cam.

They are (all intake then exhaust)
Seat to seat duration, .050 duration, lift at valve, intake centerline, lobe centerline.

The safest way to do these edits is to highlight the numbers you are going to change (and only those numbers) then type in your numbers which will overwrite the old ones but will not change any spacing which could goof things up.

Save the file when you're done (CTRL and S) or File>Safe.

Now open Camquest, open your saved engine, and you'll see your new cam specs there with an updated dyno sheet.
----------------------------------------------

What I do is go to the all out drag or some really obscure use and select a cam in that recommended list. Chances are you aren't likely to select that for anything and change those numbers.
