Some guys will think a lot about things and wonder ..... how long the runners are. Well, I guess you might want to know. Some short, some long. They worked out like this;
A took my buddy "Mic", slid him up a runner and looked into the throttle bore to see him come out from the runner. I tried to even his tip out to be even with the shortest part of the bore. The shot below is just to show. And then I took the stick out to lay on top of the runner.
The measured runner goes to the smaller plenum side. the lengths are about 4.14/4.04 for runners 3 & 5.
3.87/3.83 for runners 4 & 6
The runners2 & 8, 1 & 7 are a bit harder to measure since they run low and curve around to the other side of the intake. A tape measure was used from the inside of the throttle bore to the top of the runner. The tape measure was held level. This is just to show horizontal travel.
With the tape measure pulled level and looking downwards, I got 5-3/4 inch's in horizontal travel.
Pulling the tape measure downwards from the pad to the runners top area of the port window got me 4.40 to the car pad on the other side . Which is short the width of the throttle bores and minor space in between them.
Check picture 3. You can add approx. 2-1/4 inch's to this measurement for a good approx. length. The 2-1/4 number is from picture #4.
A total of 6.65 in length.
