Putting a 327 crank in a 350 makes it a 327. (3.25")
You can't put a 327 crank into a 350 without changing the pistons. The piston would be 1/4" down in the hole, and would have very little compression.
A 327 and a 350 share the same bore diameter (4.00"), but the stroke of the crankshaft is different. If you put 327 pistons on a 350 crankshaft it would put the piston 1/4" out of the hole at TDC.
327 Chev smallblock bore is 4.00"/ Stroke is 3.25". Just to compare , a 350 is 4.00"/3.48"
4.000 inches -- same bore size as a Chevy 350, the difference is a 327 uses a 3.250 stroke and the 350 uses a 3.480 stroke.
3.48"
The later 327's were exactly the same as the early 350's, so yes, a 350 crankshaft will fit a 327 block if it's a 1967 and up block.
It is a 325 CID engine block. ( New design ) Bore and stroke is 3.779x3.622 inches.
Buy a new crankshaft.
Different crankshaft.
Yes, but it will need to be rebalanced first.
250--- 327----350----396-----427
Yes, kits are available allowing you to "stroke" a 350 engine. Doing so increases the piston stroke by increasing the crankshaft "throw".
If the 350 engine is a carbureted engine and not FUEL INJECTED, Then remove the 327 and install the 350 and hook everything back up and your done. They are the same blocks other then the stroke.
