I'm appreciating the discussion because I also want to run the straight dump Vette style 2 1/2" manifolds. I also want to avoid a trip to the muffler shop with open manifold. I have a MIG and I'm not afraid to use it. ;-)

Although I am hesitant to cut and chop and mess with exhaust fitment, truckster's posts give me hope.

Because the ~1" stagger of the cylinder banks, the passenger side is ok and the driver's side catches the rear of the 2wd crossmember.

We're in the same boat so I'll try to post as I get into mine unless you post yours first. Then I'll learn from and follow you.
