Dose anyone know anything about these cams? The part number on it is 3929014. I have looked high and low for any info on this cam and can't find any specs on it. It has a 6-8" bolt that bolts the retainer on. Also has a different gear on it. I bought a 12v recon engine with 1000 mi on it for $500. Its a mexican STORM block. The main reason I bought it was for the block and was surprised to see this cam in it. Any info would be appreciated. Thanks
 
Thats what I figured. Was hoping to get some specs on It. If I don't end up find out the specs I'm going to take it to my engine builder and get the exact specs on it. I could put a degree wheel on and get close I guess.
 
This is what I came up with.


Intake Duration is 176.00 degrees.
Exhaust Duration is 204.50 degrees.
Installed Intake Centerline is 100.00 degrees ATDC.
Installed Exhaust Centerline is 113.25 degrees BTDC.
LSA is 106.6 degrees
Overlap is -23.00 degrees.
Intake Lift .255
Ex Lift .258

Should be somewhat close. Let me know what you think.
 
Here are the timing events on that cam;

Intake Opens 12 ATDC
Intake Closes 8 ABDC
Exhaust Opens 35.5 BBDC
Exhaust Closes 11 BTDC
