K-Member LS Swap Question

I have removed my K-member to notched for AC clearance for the LS swap. My question is since I have the K-member out already should I notch also to give more room for the fbody Oil pan? Thank You

Guys are notching it for the pan since there is some movement as the vehicle flexes under use and it's already a tight fit.

I'll be notching mine for the oil pan when I get to that point.

Some have good clearance between the oil pan & k-member, & others don't. My F-body pan was touching, so I notched the k-member.

Re: K-Member LS Swap Question

First I've heard of issues with the fbody pan and stock K-member. Does it have to do with different brands of motor mounts?
