Has anybody put 69 angled SBC center dumps on their Gbody?
Any clearance issues?

They don't fit, but there are is a model that might fit, since I have seen pictures of people who installed them.
Here's the link to center dumps with shorter angle

i can't find the picture on this computer, i will post it later from my other. Personnally, I never had an opportunity to check this.

You have to mod the frame to make a pocket to clear. Those look to be (about) '67-'72 truck manifolds and basicly all ram horns don't clear the frame. The closest set that might work (no proof they will) may be the '64-'67 Chevy II/Nova ram horns but may still need the fram mods. If there were a 100% direct fit set this guy would be using them. As for manifold options outside of the common set of the log type that cam stock would be the ones used on '64-'77 A bodies ('78 cars did use the drivers side but not all did), '67-'81 F bodies & later B bodies & trucks.

in the world of circle track racing those smaller (non Corvette) center dumps are a poor design and not worth the effort, get truck manifolds off like a 1990 they but really try to find the left one that dont have an indentation on the front lower outside part of it, these flow almost as well as the Vette center dumps, I also think lt1 camaro log style ones are really good too

I've heard the 93-97 LT1 manifolds flow well too. I'm shocked to hear that about the truck manifolds.
