Re: 1975 Corvette Engine Codes

The data tells us it is an L-48 automatic transmission car built in late March and painted bright blue metallic with dark red interior vinyl. The F 26 tells us that the build date is consistent with the VIN number sequence (Mar 26th). It should also have an emissions lable with code AS (most likely).

Steve,

Tom is correct. The engine is a 350/165hp with auto. The engine was assembled at Flint (V) on March 18, which corresponds nicely with the VIN and build date.

The fifth digit in your VIN (J) indicates the 350/165hp. If it were a T, your engine would be a 350/205hp. The third digit in your info "155420600" is probably an "S", not a 5. The S stands for St. Louis.
