I think the SB350 will have the same situation (regarding the exhaust manifold). Occasionally you'll find on the big internet auction site just the driver's side exhaust manifold. Unless you wanted matching manifolds, the driver's side is all he'd need. As I recall the Y type (ram's horn) will put the exhaust output right smack in the way of the steering box but the 265 put the exhaust output in front of it. One thing I'll add is that the SBC350 might cause the front end to be a bit higher than it normally would be...those can weigh as little as 400~450 pounds but the GMC and Chevy inline sixes were notably heavier. Your dad had the right idea in my opinion!
