Hitting on all eight cylinders Group: Forum Members Last Active: 8 Years Ago Posts: 8, Visits: 12	I am restoring a 1955 T-bird which of course SHOULD have a 292-engine. However, the cylinder heads are marked ECL-A and according to literature these are from a 1955 272 Ford passenger car OR a 292 Mecury passenger car. Not in a T-bird. The bore was nominal for a 292, 3,750". Question 1: Is there anyway to tell if this is a 272 bored to 292 or if it was originally a 292 engine? Question 2: What is giving the different compression ratios (7.6, 8.1 and 8.5) for the 1955 variants, combustion chamber in cylinder head or piston crown design? If cylinder head, which compression will my ECL-A heads give?
