MM ZA cam

Do you know your rocker arm ratio. Can you figure it out? Competition Cams Memphis Tn. Makes a 350 Chevy trailer tow grind that is amazing in a older motor. Pulles down low.
 
I could but they have a really different rocker arm set up was just hoping someone knew of a place that ground them already
 
Don't think cam cares. Rocker arm ratio is important. Newer cam profiles and degrees of separation are so much better than what you have.
 
It is a ZA with hi comp head big carb and big bore pistons runs good but wanted to do something with the cam it has some ware on it
 
Ive used Berry Cams in Minnesota, ask for there pulling grind. You could also talk to Lawrence Wilson, not sure if he does those style cams or not but has a very good grind for pulling motors. He is in North Carolina. Good luck!
