were all 10 hemi converts built at the (A) lynch road plant? or was none of them built there? I ask because I have a 69 hemi block that lists a 13 diget vin and it looks like RM27 or RM21 hard to read from the position of the block how its stored away. if it is a convet block what would it be worth? its standard bore with no repairs ever done.

All RM27J's came from St Louis plant. I had one missing the original block. It had a low number like 187xxx

Thanks, it did look more like a 1 than 7 so it was still worth checking out. so its a 69 RR block i heard they only made like 450 hemi RR in 69? or is thatwrong?

forgot to mention it was a J9A

close to 800 HEMI Road Runners for model year 1969

what's the full VIN? RM21J9A1xxxxx

800, still pretty rare. standard bore, no repairs, gotta be worth 6-7 G's
