correct throttle cable length ?
There are 3 lengths. The longest is for a slant 6. The shortest is for a stock 340, I used the 318 cable with a tall intake its a little longer thena 340 and is not stretched to reach. You can use a 318 on a 340 but not a 340 on a 318 2bbl it will be to short. Here is a 318 cable the 340 would not fit. I have all 3 but I never measured I can tell by looking at them.
