Thread: Aftermarket heads need help

Welcome to CHR Gregory!

It would help us to know what RPM the HP and torque readings are from. I would assume (dangerous - I know) that you want a gob of torque to come on just off idle. Trail riding to me does not equate to high speeds.

Is this an automatic or stick shift vehicle?

Pat McCarthy is legendary with Chevy BB and he will be able to give you a ton of advice - listen to him as you'll get no better in terms of overall performance.

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
