BigBlock,

Thank you for confirming that the 351 and 401 parts are mostly interchangeable. I still have the 401 and need to get inside to see if the rust goes farther than the cylinder walls above the pistons. If there are no other major problems, sleeves are a possibility. I already have oversized pistons that could be put to use. In the meantime, the 351C in my truck is running, but needs carburetor work, and I am thinking of switching to a Holley 500. If I put on the magnum heads and intake manifold at the same time, the truck should run better, have more power, and could be used while I figure out whether the 401 can be repaired.

We may be relatively close (less than 100 miles). Can you recommend any parts sources in the area?
