A237 cam card

[Sick Puppy]

Anyone have a A237 cam card they could take a pic of and post or email to me?
I know I have one but I searched and searched and couldn't find it to save my butt.
I got 10-12 cams with the "spares" from when I bought Mike A's SVO drag car and wanted to do some comparing of the specs including the valve events.

TIA,

Thanks Mike! I wonder why Ford didn't print the valve events @ .006 lift...

Maybe because Crane ground the cams and supplied the cam timing / events card.

0.006" is a very difficult target to get to repeatedly, as it would still be on the ramp on all profiles, and very dependent on actual lash settings. Additionally including the ramps as part of the duration is ludicrous. The end result is that it's impossible to compare different cam durations using 0.006" valve lift.

The industry standard is 0.050" valve lift and has been for at least 60 years.

That's what got me started comparing them. My "driver" SVO has a Crane A234 copy in it but I noticed the valve events between the A237 and it's Crane equivalent are a bit different. I found a link to the Ford specs with advertised duration but apparently forgot to save it. :-(
It also showed an A233 cam was available.

Found it! http://www.fordracingparts.com/parts/part_details.asp?PartKeyField=865

This chart shows the a234 minus 2* on the duration, same lift.

You must have Sheldon helping you time the cam!
