1971 K20 LS 5.3L Swap issue headers

[BR3W CITY]

The frame areas look minimal, I'd just clearance out the problem area. I'm not running a manual, but some "massaging" of the mounting ears on the auto's isn't uncommon.

I would have to cut out the hole top flange of the frame for the right and left side. The left side the collector runs right into the hydraulic clutch bracket on the side of the bell housing.

I am running DT headers and I did need to clearance the frame, just a small scallop on each side, but I reinforced the inside area, no problems so far.

I checked out your build thread a couple of time it looks like your engine sits about 1 higher than mine. so the DT headers fit better. your using an auto transmission. I still have problems with the hydraulic clutch bracket that is molded in to the bell housing I would like to use.
