i have a 1967 a-code fastback my car was produced november 9,1966 i have several 289's and im wondering what casting numbers should i be looking for? (heads, block, intake?). thanks for reading my post.
If you have a look at the engine block deck just below the distributor there is a flat piece of casting . One of the long waterpump bolts actually goes into this, you will see a stamping there , eg my 260 v8 has 3 M 13 which tells me the block was assembled in 1963 December 13. I thought this date was in fact rather early for a car with a build date 0f 06/06/64 but it might be the original engine, who knows.
