You can try calling Summit Racing 1-330-630- (maybe 0246)
need to use technical number (non 800)
I was looking for the weight of the H631CP 030 pistons. They had the
weight 567g, but didn't have the weight of the pin.
I couldn't find the info on the web either...
Keith Black pistons (www.kb-silvolite.com) have all their specs on the web.
The HB231 piston for example listed at 485g with a 102g pin.
Quite a weight difference...
Good luck

Tnx for the info. Not so sure the H400P-30 is the same thing, but that's the closest number so far. 
I'll check with Summit as well to see if they can look up the 400NP-30. I'm trying to get as accurate as possible for selection of heads to raise my compression to +/- 9.5:1. Presently have stock 76cc heads and hoping 64cc will do the trick.

Now, how am I going to transfer the .160" depth to cc? Use some guesstimates for gasket specs, deck height, etc?
