Well we're getting closer. Is it a Buick or an Olds? Can't be both. Distributor in the front or the back? Buick's 455 if built to stage 1 specs makes 510 ft lbs of torque and purrs like a kitten on the street. It is just a few inches larger than a small block Chevy and weights just a hundred or so pounds more than a small block. I had one and should have kept it but it was going to be twice as expensive to build.
