I have a 360 LA long block with small valve J heads. Cast date 11/14/72. Standard bore and appears was never apart until I took it apart to verify it was a standard bore. Motor came out of a 73 van and is very clean overall. Casting 3418496. Heads have no broken studs and motor turns freely. Located north of Grand Rapids MI. $550 for the complete motor or possible trades for small block/A body race/performance parts.
