You have made enough changes to the emgine that it will require a different fuel curve vs stock. It I’ll need a tune of some sort.

Was that the marine version? The ordinary Vortec RPM I still have does not have that passageway. That specific manifold is like 20 years old though.the vortec Edelbrock Performer RPM intake has a passage under the plenum. I routed coolant through it and ran TBI. seemed to work good...
No it wasn't the marine version. The manifold I used (7116) was probably bought around late 2012 or early 2013. I recall rbob recommending it because of these passages that you could plumb coolant too. Too bad they don't do that on their other vortec manifolds.Was that the marine version?
