305H...305G...What's the difference?
I pulled a few part numbers from my manual last night for a guy and these 2 codes made a difference between speedo part numbers.
What do they mean? I'm just curious.
Thanks...Ed

The difference between the LG4 and L69 is about 40 horse. Same torque spec.'s though.
L69 had aluminum intake, and high compression (9.5:1 rather than the LG4 8.6:1)
