I'm struggling with cam timing on my motor and I need a sanity check. Here's the problem. I've got a kind of unknown cam in Peyote--the guy who could giv; /html/fot/2005-02/msg00290.html (8,979 bytes)

(score: 1): Author: Tony Drews <tony@tonydrews.com>; Date: Sat, 26 Feb 2005 20:46:54 -0600; Bill, the specs on the cam I'm running indicate that the cam should be installed with 3 degrees of advance, and that with this advance the centerlines are Intake 106 degrees ATDC and Exhaust 112 degr; /html/fot/2005-02/msg00291.html (10,266 bytes)

(score: 1): Author: Richard Good <goodparts@verizon.net>; Date: Sat, 26 Feb 2005 22:40:55 -0500; Cam timing specs given at .050" lift are generally measured at .050" tappet lift so you would not want to divide by the rocker ratio.

5. RE: Yikes and cam problem:: HELP!!! (score: 1): Author: Bill Babcock <BillB@bnj.com>; Date: Sat, 26 Feb 2005 22:46:14 -0800; Well, I've got more rational numbers, I guess. I redid the centerline settings to 105 on the intake and then read everything with a .020 checking clearance as tony suggested. I got: intake 39.5 BTDC; /html/fot/2005-02/msg00297.html (11,153 bytes)

I tried to tweak it a little closer, now it looks like I'm retarded about five degrees. My centerlines are now 113.5 atdc for the intake and 107 btdc for the exhaust. that's reta; /html/fot/2005-02/msg00298.html (10,815 bytes)

Are you just averaging the opening and closing? There is only one centerline. You guys may jump all over me on this, but I prefer to instal; /html/fot/2005-02/msg00300.html (12,577 bytes)

I've charted the specs on three old Isky cams and eight currently available cams, seven from Erson (BFE) and one from Solow.

9. RE: Yikes and cam problem:: HELP!!! (score: 1): Author: Bill Babcock <BillB@bnj.com>; Date: Sun, 27 Feb 2005 10:09:19 -0800; Actually, I think you are exactly right. Last night at about 1:00 PM I finally got it all fairly clear, though I set it at nearly zero advance.

10. Re: Yikes and cam problem:: HELP!!! (score: 1): Author: Larry Young <cartravel@pobox.com>; Date: Sun, 27 Feb 2005 14:18:28 -0600; Exactly right! I recently took a close look at 6 different TR cams. The actually seat-to-seat durations averaged 10 degrees greater than advertised.
