    so your username must not be referring to the duration of your cam shaft then, but maybe the duration of a different shaft? :wink1: just teasing. :haha:

    Hi all

    An interesting computer program for dyno simulation is "Desktop Dyno".
    Write-ups on it place it easily within -/+5%. You can experiment with different setups by changing cam specs, advancing & retarding cam, exhaust & header sizes, intake & carb sizes & types, various heads & porting, etc....change just about everything....quite interesting....ESPECIALLy checking out different cams before purchasing.

    50k miles ago I made a bit over 400 at the crank. So I think I am more like 370-380 now.:doah:

    My neighbor builds motors (all Mopar mostly Hemi's) using programs like this and has found them to be very accurate even on 700+ hp motors.

    Side note not hijack:wink1:: His work is very cool. Some ditsributorless, fuel injected stuff. Check it out here.... www.moparengineswest.com
