So I have a 4.3L Vortec V6 I am installing in my '42 MB. The jeep already had a chevy power train (SM420 behind a 153 4cyl) so bolting to the bellhousing was easy. Trying to find a set of headers that will work with this swap. The factory manifolds and a set of headers I had on hand will not clear the frame mounted master cylinder/clutch pedal. I'd like to avoid relocating them at this time if possible. Has anyone done this swap and kept the stock master cylinder/clutch/brake pedal? What headers did you use?
