My first 50
3600 had a V8 in it when I got it. The seller said it was a 307 but I never confirmed that. The street side manifold exited at the rear then down 45* . The curbside manifold exited mostly straight down between 6 and 8. (Or is 5 and 7?) And the steering box was moved outboard about 1 1/2" with a custom mount/bracket. But it was still tight between the steering box and manifold. At the time I guessed they manifolds from a 305, but I don't know. Home made side motor mounts were welded to the frame, and a cast iron bellhousing was used that mounts to the crossmember. Looking back now it must have had the original crossmember replaced with one from a 54-55.1 truck with the sloping mounting surfaces. Behind that was the original SM-420 and 2-piece driveshaft.
