In the past 2 months we have had 2 cars that have dyno'd way less then they should after cam installs. Both were about 100 whp down from what they should have been making. After exhausting all ideas we asked them to check the cam timing set settings (both cars had their cams installed by the owners or another shop and used rollmaster timing sets).
As it turns out both cars had their rollmaster timing sets installed wrong so the cars were way off on timing. With the rollmaster's it is easy to mistake the dot posititiong as there are multiple dots. Once the cams and timing sets were installed correctly and CASE learns were performed on them they instantly made the power they should have.
If your running a cammed car with a rollmaster timing set (or other adjustable timing set) and the car either is down on HP on a dyno or is running slow at the track and no reason can be found, you may want to check the settings of your timing set to make sure they were installed correctly or did not skip a tooth.
A picture is worth a thousand words, or in this case a 100 HP. On every cam I've ever installed (over 18 or so now) I always snap a picture or have the owner snap a picture of the cam/crank dots after the chain is installed.

great job on the heads up Todd. Looking to see the info provided by Tim too. I know for a fact that John F is VERY defensive with the timing chain alignment. He basically asks anyone and everyone present to confirm it.

It should be dots facing on front, top and bottom, and inside dot on the key. Correct? Yes please post pics.
