It's been a few years, but I"ve seen an OS30 and LRP30 run in very similar trucks. The LRP had it hands down.
I never thought about it, but the 5.9 is a .36. I've never seen one run so I can't speculate how it would compare to anything. I know I like my LRP28's a lot. Well, after the break-in and about a gallon of fuel... Tune pretty easy, run with temps from 210-250 all day long, lots of rpm's and decent torque. They are thirsty though, but guessing the 5.9 is too.
I never tried the lrp30 or 32 myself. A basher friend had one in his LST2 while mine (aftershock) had an lrp28. The setups were quite a bit different, but his seemed to have more grunt than mine. I ran smaller tires and higher gearing than he did. He ran stock tires which to me always made the LST* handle like a pig and really labor the engine. The 30 didn't seem to have much issue with what he was asking of it. Mine was geared quite a bit higher than his, so I could take him in distance, but he had plenty of power to gear up.
