Friend is in the process of installing a LS3 crate motor in his stock front end 65 wagon. Changed the oil pan to a front sump GTO style and used a set of motor mount adapter plates from Speedway. Motor fit perfect and cleared nicely. Had a local guy fab a set of headers, 1 5/8" tubes, says they go in and out, no hassle, with motor in place. Anxious to see it, he's sending pics, if there is any interest I'll post them.
