3500 intake runner length

03-22-2008, 02:06 AM

imeasured with a tape measure today (rough estimate)

with head and both intakes im around 11 inches of runner length. somewhere on there someone said it was around 16 inches...is that for the 3400s?

May be cause the 3400/3100 has runner length in the plenum.

The 11 inches sounds closer to correct than 16 to me. I just swapped on my 3500 plenum last night and from eyeballing it, that seems close.

Its the 3100/3400 that is closer to 16" (~15.75" IIRC).
