how many Layer3 and layer4 ACL's can a 7600 support?

Is there any thing,that limits the maximun Number of acl's on the 7600 router apart from the numbering of the standard, extended acl's and the 31 character limit to named acl's?

regards

Yes, as the 7600 use the 6500 Supervisor II they have the same TCAM limitations that the 6500 has:

TCAM: 4,000 mask values and 32,000 pattern values for RACLs (including policy-based routing ACLs) and VACLs; 4,000 mask values and 32,000 pattern values for QoS ACLs

LOUs: 32 LOUs (64 registers) shared between RACLs, VACLs, and QoS ACLs

L4Ops per ACL: 10 per ACL (further L4Ops result in LOU expansion)

ACL Labels: 512 ACL labels shared between RACLs, VACLs, and QoS ACLs

These is a good document on COO detailing how ACL's work on the 6500/7600:
