Re: Cam considerations for speed density
sold the intake and ordered the Edelbrock. Got the cam card and it shows +4 advance is ground into the cam. My timing set has three keyways for straight up, -4 and +4 . Just to clarify I am installing the cam on the +4 keyway and not straight up right? I attached the cam card FYI

no thats wrong
they already advance it 4 degrees in the profile, its basically for a stock type non adjustable timing gear that only has a straight up mark and you'd have 4 degrees advance
install it straight up

I kind of had a feeling. Thanks for straightening that out. Pun intended.
