COPO 427 engine value??

[YENKO DEUCE REGISTRY]

Was 'MN' used in '68 as an RPO?

[PeteLeathersac]

The '68 part is probably from casting dates?.
Is it a 512 block...and is there a distrib there too, & the #'s?.
Can you lay all the stamped info on us?.
The closest BB suffix to be confused could be the MH which was an L36 Vette motor...I believe all other MN's were SB?.
As far as the $ value question goes, ChucKing probably has a better idea than anyone on what these actually will reach?.
Important is retrieving and providing the Vin as mentioned above as this could prove interesting also have an impact on the value?.

Wouldn't a 68 big block COPO motor be one-of-one?

[Jeff H]

MN would be a 69 motor. Was the casting date late 68 or is possible you're looking at a "9" in the casting and seeing it as an "8"? We definitely need more information to help out. That being said, an MN coded motor in CT would make me think Scuncio. Did you check for the partial VIN down along the flange by the oil filter?

What estate auction was it and where? Was it in a Car or engine by itself?

I tell you folks the truth and get hammered on ,someone else comes on here to jerk your chain and you all bite,I think it was at elvis presleys estate auction and they bought it for a $1 everyone else wanted the record junk.Oh and the new owner is going to bore it to a 454 just for kicks he is also going to weld up the outside main cap holes to save on bolts and just use 2 instead of 4, as for the value its worth $10 per 100 lbs in scrap.Yall have a great day and quit being suckers
