Engine # stamp on the flat...


Top
V0920CLA
Bottom angled#'s
17S4053846
My vin is 1Z37L7S405846
Here is a pic where the motor number came from, Any ideas?
I was told it was a matching # car with a TH400, and a kick down cable.
Thanks guys for helping and I will return it one way or another.

PS:CLA is the same for '77 but at 180hp, my original post came from a book that only goes to '74....sorry about that

I put 205 miles on it all ready.
The Best of Corvette for Corvette Enthusiasts
1977 L48 coupe, built around Sept. 28, 1976, engine assembled 9/20/1976, 180 hp L48 with an automatic.
Could have had a clearer picture, though.
0920 Date engine was assembled at Flint (September 20th). Time build date on your Corvette must be after 0920 since the engine was assembled at Flint then shipped to St. Louis before assembly of your Corvette was begun.
CLA Egnine suffix code for base L-48 180hp engine with AT.
17S4053846 VIN derivative. Check it again. It should match your VIN.
1 Corvette
7 Year of manufacture (1977)
S Plant code for St. Louis
4053848 consecutive unit number
1Z37L7S405846

L Engine code, base L-48

4053846 405846 These two numbers should match since they represent the consecutive unit number. Check the VIN and the engine pad again.
If your car has the L-48 base engine, she should have a TH350 tranny.
