LOST MY CASTING NUMBER SHEET AND TRYING TO ESTABLISH  312 OR 292. THANKS FOR  ANY HELP.

ECZ is the casting number for US Ford 292 AND 312 engines in the 1956 model year. You need to know the main cap size to verify however. ECZ stamped on the main caps is a dead giveaway, while some do rely on the 99% accurate "pill" on the crankshaft flange.
