Here's the Vin #: 1Y17D4L205121

Horsepower 300

Used from August 1968 until approximately January of 1969 when replaced with 3956618. Used only as 4-bolt block.

Congrats on the 74. Give it some love!

EDIT: Heres the ID decoded.
V0925WI

+1 I gave you the info and it specifically states 1969 along with the exact date of production from the ID number for the engine.

On the other link it shows you what your Nova originally came with. You did not read the page. Say it right there...


Engine Type = Turbo-Thrift valve-in-head

Displacement = 250 cu. in.

Cylinders = 6

Bore & Stroke = 3 7/8 & 3.53 inches

Compression Ratio-Std = 8.25 to 1

Now the tranny on the other hand may be the original if its a 350 Turbo Hydramatic. No way that I know of to tell if the tranny is the original.
