1952-59 Ford Ford Small block cast motor mounts ?

I posted this on the main forum but I thought I would try over here as well, I did a search and couldn't find my answer. I was wondering if anyone knew if the 351 Windsor has the same cast on the block for the motor mounts to bolt to as a 302? Year of the 351w is un known and the 302 is from a late 70's Van. A buddy of mine is hooking me up with a decent 302 and a C4 that run and drive so I'm wanting to rip out the 351w and drop the 302 in so I can drive my car. But!!! yes there's a but.....I don't want to have to redo my mounts as the 351w will be going back in once it's built up a bit

 

I believe they are all of the conversion kits I have seen to drop a late model engine into the 54 shows the 302 and 351w using the same mounts.

260, 289, 302, 351C, and 351W all use the same mount. The 351W oil pan is different from the 302. tnrotter

 

well to install a 302 in a 55 56 ford you need 76 f-150 302 mounts and use a 1 inch spacer between th block and the mount . given the 351 has a taller deck height you might be able to get away without the spacer . other wise all windsor and cleavlands use the same motor mount

 

that means 221 260 289 302 351w 351c are all the same

 

Cool thanks for the info guys
