I thought I read somewhere, maybe in this thread, that the cams were the same. The rocker ration would slightly change the duration at the valve. I know years ago I used higher ratio rockers on a couple engines to give a little boost in performance, and although not a huge gain it does add a little.

The weather, and my lack of free time, are hindering my ability to check in to the rocker ratio issue. I have a LDS and a LDT. I would like to pull a valve cover on each, set up a dial indicator, and measure the valve movement on each. This would tell if the rocker ratios are different. If...

300hp in a Deuce, now that would be scary :o

Ok, I know people have turned up LDT engines to LDS power. I am wondering if the LDS can be turned up higher yet. If the pump timing and or pressure is different, and the rocker arms are different, I am thinking a cranked up LDS will be fun. I will find out when my gauges get installed ;)

I will put my 2 cents in. I have a LDS and just recently acquired a LDT. Both trucks have the C turbo. The LDS runs circles around the LDT. I don't believe the turbo is any real difference in power. Both trucks are still as bought from GL as far as fuel settings, and seem to smoke the same...

Sounds like the only waybto know for sure

I haven't had time to search it out myself in the manuals, but there has to be a difference that is permitting more air into the engine. With out more air to add to the extra fuel it would be know different then a turned up LDT, and we all know there is a difference. It would also create more...

I am by no means a diesel mechanic, but have had my fair share of experience with high performance gas powered engines. It seems obvious that the LDS is getting more intake air in to the combustion chamber some how. My LDS has a C turbo, and runs great. So I am thinking the turbo is not the...
