71-01 Firebird - Modified subframe

[71FirebirdLS1]

The subframe got all cut up this past week to fit the LS1. I attached a few pictures here, but more are on the website. To back part of the frame was cut to clear the oil pan and the sides of the frame to clear the headers. We wanted the engine to sit further back, but everything just fell into place better moving the engine forward (i.e. '01 heater core). The engine mounts will be made from tubing welded up from the subframe. There's about 4-5 inches from the engine to the firewall.
