I would be suprised if GM would take the time to modify a pan like this.I could see it in the 409 situation but not here. Think of the cost vs them setting up to stamp out the proper pan they needed.The welding etc looks terrible and I cannot see GM putting their name on this.
We used impala pans since they we easy to get for little or nothing and we didnot want to destroy a good camaro or chevelle one.
