if its locked up, you got a rod cap backwards. Not that hard to do especially if your new to this. Also make sure your 3 and 8 caps are not swapped. I did this once and even the machine shop had given the rods to me cap-swapped. Looked the same, took a zoomed cell phone photo (love those) to positiveley ID them (plus they fit better correct, but barely!) I got a 273 on the stand that I can spin by hand, and its got pistons in it! Of course it has over 100K on them....
