this number is on right front of block of 1970 340 FW340P32320228 with iron cross after it. Does this help with what car it came out of? Is there a decoder for these numbers?
F = 1970
W = Windsor Canada Engine Assembly plant
340 = 340 CID
P = premium fuel
3232 = Wednesday, June 3, 1970 (date engine assembled)
0228 = 228th engine assembled that day
Maltese cross is a factory symbol for undersized crankshaft. If there is a number after that is would represent what specific journal. If none assume all probably .001.
I would guess a 70 swinger but should be a vin, or partial vin, on right side of block along oil pan rail.
