Can you put a 327 crank in a 350 block?

Yes, you can put a 327 crankshaft in a 350 block, as they share the same basic design. However, you'll need to ensure that the connecting rods and pistons are compatible, as the stroke of the 327 crank is shorter than that of the 350. This setup can result in a smaller displacement, which may affect performance characteristics. It's important to check for proper clearance and alignment during the installation.
