Im pulling the Y block out of my 1955 T Bird in favor of a more modern driveline. I know very little about Y blocks so I dont know if its a 292 or 312. I do know it has long tube headers and a Blue Thunder aluminum intake with the Ford ECZ-9425-B casting numbers, also has a finned aluminum lifter valley pan. It has a slight knock on startup and fades as it warms up. Will also be selling the Ford O Matic air cooled trans too. Car runs and drives right now. Bought it, trailered it home, and have driven around my neighborhood a couple times. $1000? Pics cant be sent via email. tncoupe@gmail.com Prefer local pickup as you guys know how heavy they are to ship.
