I think 3.42 will be much too fast for the power you have.
My feeling is the originalish stovebolt 6 might could pull 3.73 gears in a 1 ton but would sacrifice hauling ability. Obviously you could get along better in the flat land than in the mountains. 4.10 seems about right for actually using/working the truck. Mine is quite happy with 4.10 and only occasionally do I wish they were faster gears.
Are you sure you have 4.10 gears and not 4.56 or worse?
Hi Grigg
I took the rear cover off the rear end when I re-did all the brakes on it...It was marked on the gear set 4.10 or 4.11 I am not sure...
I think part of the problem might be...I dont know how this thing is supposed to sound at speed....If I have someone in the cab with me...you cant even talk to them it is so loud...the motor might not be wound out I might not be able to tell it is it ready to blow or not...it might just sound worse than it is...I dont know how a happy 235 is supposed to sound...I use to race one back in 1980-83...it was a straight pipe 250 cu. in. Chevrolet in a 1968 Camaro body....I cant remember how it sounded all wound out...
I am looking for someone in the Albany NY area to come drive it for me....let someone with more experience with these sounds tell me what is going on with it...
