L-48 or L82 in 1973-75

Newb question so please be gentle. According to the Wiki the 5.7 SBC 350 was available in two variants during the 1973-75 years

L-48 Years: 1967–1980
L82 Years: 1973–1980

So which one would I expect to find in a C10 1/2 ton pick up if it was stock?

Thank you,
Greg

Ain't that the truth.

Correct, but from what I can see the others on the Wiki page don't overlap the 1973 to 1975 truck years, that's why I am asking here, cause this is where Chebby knowledge comes from, hee hee

oh they did not put a date on there,
this is probably more normal

L65
The 2bbl carburetor 145HP version of the LM1 350".

LM1
The LM1 is the base 5.7 L (350 cu in) with a 4-barrel carburetor (usually with a Rochester Quadrajet) 155-175 hp engine in passenger cars until 1988.
and don't forget the 400 sbc from 70 to 80.. and lots of trucks got big blocks..

Quote:
The 400 was rated at 245–265 horsepower (gross[150–180 HP net]) through its life. The 400 saw extensive use in full-size Chevrolet and GMC trucks; K5 Blazer/Jimmy, 1/2-ton, 3/4-ton, 1-ton, and even larger 'medium duty' trucks had an option to be equipped with a 400.

Re: L-48 or L82 in 1973-75

Take a look in the generic info packets from the GM Heritage Center archives:

1973: https://www.gmheritagecenter.com/doc...olet-Truck.pdf

1974: https://www.gmheritagecenter.com/doc...olet-Truck.pdf

1975: https://www.gmheritagecenter.com/doc...olet-Truck.pdf

Those will show conclusively (no guesswork).

350 may not have been the standard in the 73 C10, but it was a big option..
