318 build!!!

stock rod length is 6.123", which from what I've seen is the same for the 340 and the 360. Correct me if I'm wrong though.

All small blocks have the 6.123" rod length.

273/318 use a light duty rod.

340/360 use heavy duty rods. 340 has floating pins, and 360 have press fit pins.

If I remember correctly, the 318 had floating pins (It's been a while). I haven't torn down any 273's to see if they had floating or press fit pins.

Even though they have the same length, there are some differences.
