a friend of mine recently bought a 327 out of a 64 el camino. turns out the block is cracked. we found a good 350 block to use and would like to use the steel crank from the 327. does anyone know if someone makes a main bearing that would allow the use of a small journal crank in a large journal block. thanks
Try Clevite 77, pretty sure they do. Just call summit or email Clevite directly.
Also take off the timing cover on your block and see if it says 10/20 or 20/10 if so it's a good block. This number indicates extra metal in the block. They also come with 20 alone (I believe, or it might be 10 alone) and nothing extra for an emissions block (lighter).

jeff, i had the same deal. small journal 327 from a 64 impala had a main stud break off when i was rebuilding it. removing the stud cracked the main bearing saddle. i still have the crank/rods/pistons in the garage. i havent seen bearings that would work with a large journal block so far. and im not sure if i would want to go that route. thats a large amount of copper and lead that your relying on to hold that lower end tight.
sure thing, if I remember right they cost around $300. They said that they get most of their sales thru NASCAR and other racing guys, wanting less rotating mass and friction. I am trying to find or see if they make them for the rods also. Let me know if you find anything.
the stroke is the same as a 307 crank. we were just trying to use the parts that we have plus that is a damn nice steel crank. the bearing spacers are over $200 dollars so we might just use a 307 crank. the website that cornholio sent were the cheapest at $202.
