in any case thank you for your intervention because it is really very very complicated to find information about these camshafts 😞. in addition in France we are not necessarily specialists in the American v8, so to find references it is very complicated. I came across a similar subject on another US forum the person apparently had the same style of camshaft as mine and same struggle to succeed in finding the values.
I will have it checked and as soon as I have the answer I will put it on the forum, it could perhaps help others 😉

 

Yes it could be helpful. These could also be custom ground cams, so without the cam card you're pretty much stuck measuring if you don't know who made them.

 

yes and i think that's exactly what happened.
apparently the camshafts were taken off a mustang that was heavily tuned with a serial number specific to the car. so chances are an engine tuner decided to make cams just for that car. that's my hunch.

 

Yeah more than likely

 

Take them to a machine shop that has the equipment to measure the cam lobes and determine the opening duration/lift.

 

Hello everyone, I got some feedback on the measurements of my camshafts.
Do you think the values ​​are consistent?

exhaust lift (without rocker arm)5.67
intake lift (without rocker arm)5.65
Exhaust duration 180°
intake duration 168°
Crossover 86°
