What's my 78 400ci 500557 YA motor worth?
« on: July 18, 2011, 08:48:53 AM »
I pulled a 78 400ci motor out of my 79 car.

I believe it's a 4-speed motor
Block number 500557 and stamp YA
It has the 6X-4 heads and chrome valve covers
Complete and running when I took it out this weekend.
Does need a rear seal though - minor leakage when parked
