Default What engine do I have.

Can anyone tell me what engine I have in my 76. The numbers I found are 3970010 on the back of the block and VO229CMD-121558897 on the front near the passenger side head.

Thank you for your help.

3970010 - 350 Block casting number used from 68 to 80 with either 2 or 4 bolt mains.

VO229CMD-121558897

V is the Flint engine plant
02 is the month of engine assembly
29 is the day of engine assembly

CMD in 72 denoted a 350 2 barrel with THM 350 with A.I.R./Smog CAM(Calif), NB2 Not sure if the same held true in 76.

121558897 should be part of your VIN if its the original engine.

Does not appear to be the original engine. Last 9 digits should be the same as the vin. My '76 is l6s429750.

From what I found the CMD is as follows:
Car type
1974 CMD 350 tur 350, taxi - 2 full size
1980 CMD 305 LG4 H 155 4 G

It is not a corvette engine. Check www.nastyz28.com they have lots of great block info.

I kinda knew it wasn't the original motor when I realized it was suppose to be painted orange and mine is blue. But I didn't know enough to check before I bought it and the guy said it was the original engine. I took him for his word. I paid $6500.00 for it and I liked it at the time. It needs an interior and some other things but it is paid for.
