I myself was asking because I just had a 318 assembly balanced, with a set of 340 rods I had lightened a bit and kb399 domed pistons and it turned out to be 2098 grams and they took just a tiny bit from the crank.

Just wondering what oem was on a teener.

kb 399 piston weighs 552/132. Stock weight for a 318 piston was 591 grams. 360 was about 20 grams less. Pin was, I suppose, same as that listed above for the 360. Later 318s, I mean 1973 and up, used the 645 rod so the bobweight would be about 20 grams heavier than for the 360.

The early 318/273 rod was 726 grams, the 340/360 rod was 758.

The 645 rods weren't that much different than chevy 454 rods. This is my way of pointing out how heavy they were. It's easy to save 120 grams per rod by switching to aftermarket rods.

Check out the KB/Silvolite website, they are clearancing some pistons.

I was actually looking at that list earlier in the day.

I got a killer deal on the 399-s im using, although not from them but needed locks for the floating pins and they are not super easy to find the ones they call for.

I emailed united today asking if they would sell me 16 and they are sending me them for FREE.

We all spend good money on our projects and from time to time even the smallest purchases end up with the company throwing the dog a bone.
