The Windsor and 302 are the same block, just bored out larger. Usually a 302 was matched with a C4 which is a different length most times than a C6, so you might need to have your driveshaft shortened. My Dad and I did a lot of 260, 289, 302 and 351W swaps in late 60's early 70's cars with the only changes being the oil pan if the front running gear of the donor car was different.
