Howdy folks! I tried a search but didn't turn anything up, but I suck at this interweb thingy so I may not have done a good search.

I'm looking for info on how to identify a 302 vs a 351W while it's in a car. I'm looking to swap a mid 70's Granada driveline into my 1950 sedan, and I understand the Granadas could be had with either a 302 or a 351.

Does anyone here know how to easily identify which is which while it is in the car?

Thanks!  

The 351W has an inch taller deck height vs. the 302. The easiest way to tell the difference in the car is to look at the distributor mounting area in the block. On the 302 there's no reinforcing ribs, where as on the 351W there are two vertical ribs that reinforce the block wall in that area since it is taller...


Here's a good site with info and pictures:

I have also found if the alternator bracket bolt is in the top hole on the cylinder head, then it is a 302. If the bolt is in the bottom hole, then it is a 351. Has anyone else noticed this?  

If you ever get a chance to look at a 351W and a 302 side by side I think you will also see that the 351 intake is almost 2 inches wider than the 302.  After you get accustomed to seeing this difference it makes the 351 pretty easy to spot.
