Thanks guys!
Both are just as reliable as the the other?

Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
All that concerns me with doing that is losing the multifuel capability.
I agree with you RED , the ability to burn the oils will still be there since we're not changing the compression ratio (22:1 just like the 6.5 diesel) . Going with the better Turbo will also help since we will be bumping up the fuel. More fuel needs more Turbo to keep the EGT's down. As far as the Stanadyne pump being able to handle the oils, a lot of guys are already burning waste and Veg oils using the Stanadyne with no problems. The biggest boost to my confidence in wanting to do this is that Tracey mentioned people who are already using his mods on their tractors now with no problems.Losing the ability to burn straight gasoline might be lost with the increased air from the higher boost and more efficient turbo. Ability to burn oils though won't be lost.
Was that Hercules only or White as well?Talked with Tracey tonight. He gave me some more information that is rather enlightening. It seems the military had Hercules use a different crankshaft in the early 1980's to cut down on cost. This crank was made from 1548 tool steel. The cheapest tool steel available ! This could explain some of the problems people have had with there bottom ends going out. There is no way to tell from just looking at the crankshafts either. It takes a metallurgical exam to tell ie: cut off a sample. The normal crank is almost indestructible, being made from 4140 forged steel. .
This information came to Tracey from his engineering friend at the Hercules plant. Was White making engines for the military at this time ? If so then they probably also would be using the cheap cranks.Was that Hercules only or White as well?
White would have been making engines for both the military and their tractors (apparently from 1976 to 1988 http://www.tractordata.com/farm-tractors/000/5/7/570-white-2-155.html )This information came to Tracey from his engineering friend at the Hercules plant.

According to Tracey you can see no difference. He had bought 10 cranks for his pulling tractor. After modifying them he found out about the different materials used. So he sent in samples of each crank. Six where the 4140 and the other four where the 1548 material. He decided since he had already paid to modify them he would use them. The 1548 cranks would only last one pull. He still is using the original cranks in his 5,000 hp engine, but he tests each one to make sure they are made from 4140 material before modifying them.If that were the case you should be able to see the difference between the two if you lay them side by side.
