Choosing a camshaft for my flathead

I have a 40 mercury flathead that needs a camshaft. I am using a offenhauser 2x2 with 97's. It is all stock besides the intake. What cam should I buy.
 
I've been a fan of Iskenerian for decades. You might want to look up Isky Cams and give them a call.




Isky Racing Cams

They have about 4 grinds for the venerable old flatheads.

Patrick,
I ran an Iskenderian 400 Jr. in my 1/4 X 5/16" Flathead, with 3 2's. It was a good all around running cam.

I remember the '400' as a comp cam with a nice rough idle [ I like that] that worked well on a good hot street engine. I don't know if they make it or have changed it over the years.
 
The 400 jr. in my opinion is too much cam for a mild street engine like yours. I would use something milder, like a Winfield SU1R
