I actually have 2 248s, one with a 477 and one with a cracked 819(stock to the truck). I also have a civil 302 long block with 2 bent rods and in need of 2+ sleeves but with a good head. I am making arangement to buy a 52 military 302 that runs but is 5 hours from me. A 58 270 is for sale by me but the engine is condition is unknown and I get to pull it for $600. I am thinking I will build the long block and keep the stock manifolds until I can build or find an intake and header.
