Firebird LS engine placement

[Jk918]

The holley mounts seam to be the most preferred option for ls swap 1st gen camaro and firebird. I'm running basically the same setup as you with engine in the rear most positions and basically finger tight to the firewall. The worst part was getting the headers to fit with the power steering box. I'd try moving it forward one and see how things line up. Selection of headers also can make a difference in clearance around the steering box.
