Trust me I know about down low torque for off-roading. But it is all relative, since I come from a "mild" SBC in my last CJ-7. As much gearing as I have I am rarely below about 1000rpm. I am running a 3.77 1st gear, 4:1 low in the t-case, and 4.56's in the axles as of now. I will be running a 6.32 1st gear, 4:1 low, and 5.89's by the time summer is out. After talking to my machinist, I am probably going to just have them square up the heads and block and call it a day. He say that with those pistons and how my motor looks now I will be at 9.66:1 just squaring it all up. I was told to get as close to 10.5:1 to get the most out of the propane, and then just back the timing out to get it to burn premium on the street. That is the only reason I was looking for more. I do not mind having to run high octane fuel, I did it for 4 years with my CJ-7 as the SBC in it was at about 11.5:1. As for daily driving... it gets taken on the road on nice days around town and to the lake. Anywhere else it typically gets put on a trailer due to the gearing.
Anything else I should think about?
Thanks again for your time,
