I'll bring the photo of me with my 55 Studebaker President. It was bored and stroked to a little over 300 inches with a balanced assembly, ported heads, healthy cam, and 650cfm Holly. The axles had the poor man's posi with welded spider gears, traction bars, and a Schaeffer aluminum flywheel/comp pressure plate. As I recall the forged pistons gave somewhere about 11.5::1 compression ratio. I ran fairly open pipes and the thing sounded and ran very strong. The interior was from a '64 GT Hawk and had way cool buckets and a Hurst floor shifter on the 3sp, O/D gear box.
