I found a 455 core, but had to drive to Waco, TX to get it. I've got (2) BBB 455's now, so I will proceed to build a Torque Monster that will live in my '78 Buick Century.
Thanks Robert for the response. I'm after all the cubic inches I can get. I've got (2) 455's now, and I am negotiating a 3rd one as I write this. The BBB's are getting harder to find. I will keep it in mind. See you soon.
