Thread: Low Vacuum in 390

Tweet

I was hoping that the cam would not be responsible! I guess im just not keen to pull it all off again and check. Im going to do some final checks with my vacuum gauge today because its such a glorious saturday morning to slave over a 390!

Hworrel, you were saying that you lost a championship once because the cam was out a tooth.. Was it still running ok or was it really noticable?

Ive attached my cam specs to this post just to show you all becuse alot of other blokes reakon Ive got a really bad combo thats why there's really low vacuum.

Cheers guys.
