Material make up of the Chinese Dart look alike block
I first have to that Leo at http://www.rlengines.com/ in conjunction with Turbocam which performed an Optical Emission Spectroscopy, I will add Leo has been working on a new anti-wear treatment TX-1 for performance components http://www.rlengines.com/tech/TX1.pdf Guive him a call for more info.
Some of the Key ingredients in cast iron to make it strong are Nickel,Molybdenum, Copper
The Little-M nickel content is 0.149, Molybdenum 0.211, Copper 0.404
Dart SHP Nickel content is 0.071, Molybdenum .016, copper 0.283
Chinese block Nickel content is 0.005, Molybdenum 0.005, Copper 0.020
Leo did the Brinell test by using the Rockwell B Scale and converting it to Brinell scale and he will back this test.
Little-M tested 200
SHP 190
Chinese block 107
I am sure the chinese blocks will very from block to block and now I see why when I had to line hone the chinese block it kept loading the stones up as it was extremely soft.

Looks like more Chinese junk to stay away from. Thanks Hink.

If ya check close enough you'll probably find they might be about 5% Bubble Gum! :shock:

Some more info from Dick Boyer at PBM
Some more info. on the PBM block by Dick Boyer from PBM
Not very impressive numbers
Turbo cam that did the testing did not feel cabon was a major player with cast iron as you could throw a LOG in when its being casted and it would be high any how.
I will compare with your specs to the Little-M only
Silicon Dart 1.270 PBM 1.630
manganese Dart 0.663 PBM 0.930
Copper Dart 0.404 PBM 0.320
Nickel Dart 0.149 PBM <0.01 which mean less then
chromium Dart 0.194 PBM 0.320
Titainium Dart 0.0058 PBM 0.052
Molybdenum Dart 0.211 PBM <0.010 which means less then
Aluminum Dart<0.003 PBM <0.010 which means less then
Vanadium Dart 0.0059 PBM <0.010 which means less then
Lead Dart <0.01 PBM <0.010 which means less then
Magnesium Dart <0.002 PBM <0.010 which means less then
Tin Dart 0.0058 PBM 0.004
Iron Dart 93.2 PBM Not mentioned
I have no record of Sulfur or Phosphorus
With no Nickel and no Molybdenium and low in copper I can't see how it would Brinell test very good but I am not a metal guy either.
I am sure there will be someone that can shed some light on these numbers.
Thanks for posting

NO SECRETS! THE TRUTH! The dyno test on the engine I built was performed by a PBM customer that does not want to be involved in this. All we want here at PBM is to give our customers a good product that performs up to there expectations.
