LS3 Manifold Intake Manifold Volume

[danall]

I see a number of different values used for Manifold Intake Volume in LS3s. I have the common 12602477 intake found on a lot of crate gen4 LS3s. I see different values (from the repository) for manifold intakes from stock LS3 tunes of 9.59, 13.487 , 10.5 and 14.0?? Anyone know definitely what volume (not flow numbers but static volume) should be used with that intake manifold.

You must be looking at car vs truck manifold volumes

Nope, these were car tunes from the repository, most identified as "stock" tunes.
