Hop up for your Willys hotrod. The Supersonic head raised the compression ratio from the Willys 6.48:1 to 7:1 giving 8 more HP for a grand total of 68. Bottom image shows it all spiffed up.
I wish I knew how that when I was in high school driving my 1946 Willys CJ2A flat fender Jeep. That extra HP would have made her zing! I’ll bet it might have even hit 50mph !
