Searching for L78 396
 

I stumbled upon this older add from 2007 for a 396-375HP L78 engine. I have attached the add to the post. Turns out this is the original engine for the Chevelle that I have owned for about 30 years. The engine was gone when I purchased the car. The T0310JD B362705 match the numbers on my build sheet exactly. The gentleman that posted the add no longer has possession of the engine nor does he have any information about the buyer. If anyone has any information on this engine, please contact me at 724-272-1162. I think the seller lived in Ohio when the engine was sold. I would love to return this engine back to where it started life. Thank you very much. I appreciate any help!

Well this one dragged me down the research rabbit hole on Saturday. From what I can tell, at the very least, it's from a 1972 Buick Gran Sport (GS)

Highly doubt it's 1 of the 4 GSX with a 4-speed in '72.:grin:

Only 7% of GS cars in '72 were 4-speeds. (8,575 total)

Looking for any drivetrain part, MO engine, Muncie trans, or 12 bolt with 18437179 stamp.

Full VIN is 124378N437179.

I have the complete owner history of this Z28 from when it was purchased new, through out it's racing history, to me, the current owner. 4 owners total, but I'm just the second registered owner since the second and third owners only raced it.

Original owner confirmed and documented to me that he ordered and took delivery of this 1968 Z28. Bob Johnson, high performance manager of Scuncio Chevrolet and well know drag racer and drag car owner, also confirmed and documented the car in person, as a true Z28 he took in trade at Scuncio, and as one of his 12 or so personally owned drag cars.

11,000 original miles, all original body panels, original deluxe interior, original vinyl top, 6k red line tach, 15 inch wheel decal in glove box, etc...

Thanks.
