302 should be MO or DZ. No such thing as a four bolt main 327. The TBM leads me to believe it was originaly a truck application.
This is what my experience tells me.

i take it as "TBM" means truck block motor? the oem color of the block was blue and it came out of a late 70's utility truck. we have several sets of 4 bolt main caps that are good but none of them match up to the grooves in the bearings also i have 3 blocks that have 010 or 020 stamped into the timing chain area arent these the good blocks persay?

I agree with Metric. The only blocks I have seen that number on are 350's. In fact I have 2 of them with that number on it now, must be a common one. Some are 2 and some are 4 bolt.

I had this very same problem; being told my engine was out of a 69 Camaro SS. I was told it was a 327, but when I ran the numbers it came as a 302 327 or 350. An engine builder told me to take a look at the crank flange. 327 was supposed to be round, 350 more squared, 302 more rounded also. I also found (can't remember where) a place on the net that showed you the difference with each engine flange. I guess a lot of people have had this problem. Mine ended up being a 350 010 4 bolt with stock flattops and 462 humps.

Best way to tell is to pull the pan and check the crank numbers or pull a head and ck the bore and stroke.
