Timing Chain and Balancer Advice
« on: June 08, 2024, 11:56:43 PM »
It seems I jumped timing during some "spirited driving"--an interesting event for problem solving skills.

What timing chain set and balancer are best for a mild street 390? It seems there are some variations based on who manufacted the cam (for the timing set--dowel placement). I don't want to order the wrong part, but don't have it apart yet. Based on documentation from previous owner, this engine has a Bullet cam in it (though this is a paperwork-based assumption).

I searched previous posts, but tech does change....

I have always been satisfied with the Ford Performance timing set, M-6268-A390


I know there are higher end parts available but for a street engine I think they are fine.  Our "real" engine builders will no doubt have some recommendations also.

I really like the Ford Racing sets for flat tappet cams.  I use Cloyes billet sets for roller cams.

It’s hard to beat a Powerbond balancer.

What is the deal with the variations some manufacturer's list regarding engine crank to cam center measurement? Is this something I need to be concerned with when buying? It seems Ford Motorsport only shows the one P/N without any CL variations.

You've got to wonder, who makes the timing sets for Ford Motorsport, since they pretty much just put their name on the packaging.

Can't promise, but up to at least recently the Ford sets were made by Cloyes

The Differences In Crank To Cam Centerline Measurements Are Usually To Make Up For Engines That Have Been Align Bored/Honed. Takes Care Of "Sloppy" Timing Chain, At Least Untill They Are Ran A While.
