Quote: I am about to put a non-numbers matching 426 Hemi into my 1966 Belvedere II Hemi car but would like to know where this donor came from, i cant decode the engine number - help! Date: 5-19-69 Eng ID: 7C219753
On a 66 there are no stamped vin numbers on the block. All cars 1967 and down actually. So if you found a 66/65 casted block it would be "numbers matching" in the 66 sense.
Usually 66/65 blocks go for less than 69's. It should not be very hard to trade across a 66 for 69 block in equal condition.
You can ask here what casting dates are typical found/accepted for Hemi cars near your SPD date.
