LSXRT Runner Dimensions
Does anyone know, or have an LSXRT that they can measure, the dimensions of the runners. I know that they are 10.5" in length but I would like to know the width and height of them.
I'll keep searching and if I find what I am looking for then I will update this thread but for now I am stuck.
Thanks

I really wish I could find intake manifold dimensions. I would love to pair the right cam with the right runner length, but there's just no dimensional info even on the stock stuff and its hard to measure it just using calipers and snap gauges. I thought this manifold has the different length runners you can install in it, maybe it does I just can't find it, I know its 2 piece so you can take it apart.

That is correct there are 2 or 3 runner sizes actually. I found some measurements once but idk how accurate they were so I never posted

Yeah there is also inconsistency because some of the runner lengths may inadvertently include the intake port runner length in the cylinder head as well. I feel like there is a lot of optimization to be had in getting the correct intake runner length for the right cam choice. I think the same goes for the exhaust runner length (header collector and merge length). I just don't understand why all longtube headers are all the exact same length, usually there is 2 or 3 primary and collector diameters but they seem to all be the same length and the manufactures never release that either.

It is so you can't reproduce it mainly. I don't know why either, just cringe

I really love that LSXRT just because it looks so damn sweet but at the same time the TBSS is worth more bang for your buck. I'm big gay and like the sexy intake manifold look to flex on everybody when they check under the hood. Plus I don't have a beauty cover so...
They didn't include any holley on there though and I didn't see any in thread.
