anyone know where i can find a chart to i.d. my block. I found one once but can't seem to locate it now that i need it. I found a block in an neighbors store room the other day. im prretty sure it's a 350, just don't know the specs on it. He thinks it came out of 73 lesabre but is not sure. #'s are as follows. #'s on the deck are xc 383 #'s on rear area 11 1241748
X's were used for the 1973 modelyear XC = 350 V8, 150 hp (new ratings), 8.5:1 compression with 2 bbl carb, used in 3 speed cars only.
