| RE: 360 with 390 or 427 crank |
| By Gerry Proctor - 07/08/2002 3:48:06 PM; IP 207.133.188.254 |
| All FE cranks (except for the 427 NASCAR version) share the same rod and main journal diameters and widths so, in theory, any FE crank will go into any FE block (with the exception already noted). As a side note, the 390 and 427 share the same stroke so replacing a 390 crank with a 427 crank gets you nothing in the way of a displacement increase. The trouble begins when you start mixin' and matchin' parts. Oddball stroke and bore combinations can leave you with few alternatives other than expensive custom pistons. Now, fortunately, a 360 has a 4.05" bore...same as the 390 block. Which means that if you use 390 rods and crank, you can order off-the-shelf .030-over 390 pistons and end up with a 396. Unless you are building this as a high-rpm endurance engine or intend on aspirating the engine, you'd be dollars ahead by avoiding the 427 steel cranks. |
