I mocked up my 350 SBC and 700R4 some time ago and just squeaked by with the ram horn exhaust between the motor mount and original steering box. Since install, I am off my original design. This is on a straight axle front end. Not so concerned with power steering. I looked at the Toyota mini box but still will not have the clearance I need for the exhaust on the driver's side. Block huggers won't work. Rather not run fender headers. If not familiar with the 46, the steering box is located in the frame rail instead of the top like the AD trucks. Here are my thoughts:
Option 1: Move Steering box back 1-2 inches with drilling out new sector hole in frame and shimming steering box so the sector is in the same plane as before and extending my drive link. I have put in modern tie rods with an adjustable link. I am not a machinist but thought this would be less disruptive to the steering geometry. I have also cut my steering shaft on the old box and will U-joint it to my modern steering column.
Option 2: Try the Toyota mini box on top of the frame as the AD modifications have done and extend the pitman arm. Not crazy about this as I fear it will really mess up the steering geometry.
Option 3: Leave as is and reverse the exhaust manifolds out a 1980 Camaro, for example, so my exhaust exits toward the front of the engine and then turn the exhaust backward.
I have attached a pic of my issue and an example of the manifold. I have plenty of clearance on the passenger side.
