Sorry for the confusion tcederlman. The truck is a 46, but we got a 1954 235 for free and had the 1954 engine sent to the machine shop to be rebuilt.
The repair shop found the 54 exhaust manifold to be warped too much, over.030" and the metal too thin to resurface.
But my search is over, I hope. Yesterday my son found a clean low mileage 235 that came out of a 1958 Chevy Biscayne for sale on Long Island for $350.
I went and saw the engine today and bought it for $230. The engine sits in my garage now. Tomorrow I will take off the exhaust manifold.
Jerry you are right about better to keep things stock.

Edit Sunday morning because I left out the year for the engine I just bought for the donor exhaust manifold.
