Thanks Glenn, the horse power peaked @ 6700 rpms. I got the rev limiter at 7000 rpm. No I dont have High speeds due to all the gear reduction. It is a standard transmission that I always run 2nd gear in. I calculated my wheel speed with my tire diameter and it came up 37mph. I run a profab transfer case that has quick change gears, right now im running a 1 to 1.5 gear. If i could get somewhere in the 650+ hp range i could go to a 1 to 1 ratio and get somewhere around 42 mph wheel speed. Yes I would like lots of torque to come off idle. Some of the mud we run in is really sticky. I have seen some 800 hp motors bog down in the mud and I'm thinking it might be due to low end torque. I have heard you can build horsepower with low tq or build it with torque and the horsepower will follow, like I said im really not a master engine builder by no means, I am a fabricator. I do however want to become a better mechanic in the future. Thanks again
