Poly 318 Intake-Single 4 Barrel
$400 and up is the going price either used or new.
The poly had more torque than an LA.
I really liked the one in my first 66 Coronet...but...
the motor was so wide I had a very difficult time convincing all the gm owners they just got beat by a 318!
The Coronet "440" badges on the fender didn't help either.
