My car is a C code, so it is a 289 2v car. The PO told me that he had the engine rebuilt, including .30 over pistons and the appraisal that came with the car mentions that it is the rebuilt original engine. I have the car into my shop right now, as one of the heads is cracked and I am going to have that issue addressed. Today I went in to get the heads, and my mechanic wanted to talk to me about the condition of the block. Turns out the pistons have uneven carbon burn on the tops, and the some of the bores are scored. He told me that this is due to the rings not being seated correctly (if I remember correctly). He is going to tear the block down and get it to a machine shop to see what we need to do. Probably going to go .40 over. Hopefully the cam and internals are ok.
We looked at the number stamped into the rear of the block and it does NOT match my vin. The number is 8K13 76. It might be 8R, but I'm not sure, as it is pretty faint. My vin is 8R01C150245. In the valley of the block is cast 302. I have heard that towards the end of the run of 289s, some cars did end up with 302 blocks. Is that correct?
Sorry to be long winded. Any input would be appreciated.
Thanks.
