How to identify a s52 block

[32VALVES]

this guy on craigslist is selling a good s52 short block for $200, so I need some pointers on identifying it as one, cause I havent been around 24v motors really to tell the difference...

[gregslow318i]

should say 3.2 on the block casing by/under the starter

Really, I figured since it was just a bored out M5x it would just be a 2.5 stamping, as the castings for the outside would be the same, never really looked at mine. Anyone else verify Greg's statement

like greg said, there is a small smoothed out area on the drivers side of the engine near the motor mount arm. it has a series of numbers stamped in it and the first 2 #s designate displacement. "32 345 5694" its a 3.2 (S52).

I had the same question which led to the link of designation the difference.

Here's the original thread.

Just ask it when you get there. "Are you a 3.2 block? aka s52?"
