wild cam vs. bottem end torque cam

In my opinion,if you do any off roading,where you spend most of your time crawling slowly,a cam that is suited for high rpm will be a bad choice--the truck will be lurching and jumping and wanting to stall at anything under 1800 rpm or so--not what you want for off-roading at all--They have special low rpm cams for towing,off road and trucks that carry heavy loads that work very well,on the street as well as off road--its not very often you have enough room in traffic to wind it up over 5000 rpm,at least where I live!.
My brother has a 70 454 that was in a 1 ton 82 K30 4x4 with a SM465 tranny--when he first got the motor it had a "full race" type cam,it idled poorly at anything under 2 grand,and plowing with it wasnt very easy,and on the street you had to wind it out to get any power,lugging it in city traffic fouled plugs and was very herky-jerky. He yanked that cam out when he decided to do the timing chain,replaced it with a Competition Cam that was specificaly ground for lower rpm use (1000-4500rpm)and it was a tourque monster--you could now leave it in third gear nearly to a standstill,punch it and it would light the tires right up,no lurching or jumping,and it was a pleasure to drive it after,nice smooth idle,very forgiving on the clutch,used to always want to snuff out when taking off from a red light until you got it past 2000rpm with the old cam--he had a weiand intake with the "angled" carb mounting base with an open plenum too(better suited for racing at wide open throttle than street use)and it still idled and performed well under load!.Too many time people think "more is better"when choosing a cam (or carburetor) when actually many times engines run better with a milder cam or smaller carb--I used to hear at the track "leaner is meaner" many times--when a guy with a 2 barrel carb turned in a better E.T. than he did with a four barrel carb!. /forums/images/graemlins/crazy.gif

Other than building in bad clearances, overcamming a motor is the worst mistake a person can do.
I still have that problem too /forums/images/graemlins/screwy.gif /forums/images/graemlins/screwy.gif /forums/images/graemlins/screwy.gif /forums/images/graemlins/screwy.gif

I love the way it sounds, but fortunately, I've never made the mistake of buying a cam that was too big.
When I built my first engine for myself, an old man told me, "If you think it's too big, it IS! Get a smaller one"

Look into getting some "Rhoads" lifters. They are variable duration and lift lifters. If you use them with a cam that is a bit more then you should have gotten it will work like a smaller cam at low rpm's. I haven't tried it but from what I have heard they do work...but are noisey.
