ls swap im my 61 apache
 

im having clearance issues with my exhaust manifold because i raised my crossmember up. i now i can use vette manifolds but im not sure what will work better? its a LS 4.8 L motor out of a silverado

From the research that I have done a set of Trail blazer SS manifolds would work for you.. My truck is a 72, but the pistures you posted look very much like mine... Hope this helps.

I'll second the TBSS manifolds. Or are the 63 frames narrower then the 67-72?

x3 on tbss, check my build, i squeezed them in my '66 next to a 4l80e

I've heard the new camaro headers fight tight to the block, but the issue is the angle of the output.
The tbss manifolds have output flanges that tuck pretty close to the block, and clearance the perches and frame.

Ok Kool thanks.and I don't think it's narrower but I did raise my crossmember to clear the ground .one plus is I can keep the ax compressor in the factory location
