I will be installing my new 312 in my '55 Customline sometime in May hopefully. This will leave me with an extra engine that I will have no use for so I'm testing the waters here to see if anyone would be interested in all or part of what I will have available. Here it is: Running 272 - mileage believed to be 92,000. Puffs a little smoke when flogged hard so rebuild probably is in order. It has the "B" intake and '57 up distributor. ECZ-G heads and rebuilt 1.54 rocker ***emblies. I also have original heads if interested. The cylinders showed no discernable ridges when I installed the heads about 5 years ago. It has a rebuilt 450cfm Holley w/manual choke. I have two starters, one 6 volt and one 12 volt. I have a 12 volt generator that will go with it. I am keeping the '55 harmonic balancer, but will include a '57 balancer (narrow pulley) and water pump pulley. Has dual exhaust manifolds. I'm open to suggestions/offers. Thanks for looking.
