Without seeing a cam card it's hard to say |

Sig Erson's old cams were often given big advertised durations but had very low duration at .050". If you like the old cam why not keep using it?
The Performer RPM FE has been a disappointing cam for everyone I have ever talked to who tried it. It is doesn't have enough duration to be a good race cam. It has too tight a lobe center displacement to be a street cam. Just an unfortunate combination. It has a really wild idle sound but is no more powerful than cams with "frisky" sounding idle.
Here's another recent discussion on the same cam: http://www.network54.com/Hide/Forum/message?forumid=74182&messageid=1073350258 |
