I currently have a CUCV with a mild cam 383/th400/4.56/31.5" tires. The truck never sees over 3500rpm. I am looking to swap a 6.0 lq4 into the truck. I would like to know if there is a cam that would make better torque than stock in the low range. I don't want to do any other modifications to the engine.

There's also Comp Cams # 54-408-11(206/212 112lsa+2, lift .515"/.522").

If you are looking for something on the cheap, these cams work well in your application.

2001+ LS1 Corvette cam
198/208 int/exh @ 0.05" duration
0.500" / 0.500" int/exh lift
116 LSA

2001 LS6 cam
207/217 int/exh @ 0.05" duration
0.525" / 0.525" int/exh lift
116 LSA

FYI, These cams will have LESS low end TQ than the factory lq4 cam, so they're wrong for his needs/intended usage.

Out of all the 6.0 trucks we've owned our 99' 3 door was by far the torquiest and fastest and it came with the same cam as the 5.3 191*intake 190*ex .456-.467 114-2 I'm telling you this cam straight works in a 6 liter and can be scored cheap, plus you don't need to change any other parts, when they went up to the 01 lq4 196-207? Cam on a 116lsa the torque was gone!

I am not looking for any custom grind cam and I don't want to swap out springs/retainers, etc. I will look into the cams listed above. My plan was to just drop the engine in with out changing anything, but maybe changing the cam, intake, exhaust would give me some more power in the low range.

I feel compelled to tell you a story......

20 years ago, i ran a fuel injected alcohol dragster and pulled it with a small block Suburban. We blew the engine in the Suburban, so we needed something new. The question was a BB or SB. Since we had the truck set up for a SB, that was the choice.

My thought was to buy a small passage Edelbrock manifold and a 390 Holley carb to keep the mixture velocity up and make some torque. But, i had no idea what I needed for a camshaft, so i called Chet Hurbert. He had reground the dragster cam and it went .9 quicker with the new cam, so I thought he was the man.

He asked me what i wanted from the cam and i told him. I wanted torque for towing and was trying to keep mixture velocities up to promote increased torque. He told me I was on the right track and he had the perfect cam for my intended use and combination, so i told him to send me one.

Bottom line was the truck pulled like a BB up to about 4400 rpm and then it was out of breath. But it did EXACTLY what he said it would.

Now I wish i had the knowledge to suggest a cam for you, but I don't. There are members here who have that knowledge and some who don't, so my question is how do you know which advice to follow? Tough choice....

My advice is to call one of the trusted vendors on this site, tell them what the cam is going in and the desired usage and they will recommend a cam that will work. Buy what they recommend and don't look back.

My guess is your new combination will work every bit as good or better than the one Chet ground for me! Good luck with the project.

Now if you don't mind going with a custom grind, here's one for you to consider that'll give a little bit more power down low, but will still offer long valve spring life.
210/214 112lsa+4, lift .556"/.559" lobes are Xtreme RPM high lift lobes are #3708(210*), and #3710(214).
If you're willing to sacrifice some valve spring life for even more power, then swap the #3708 (210*) lobes for a XFI #3012(210*) lobes with .595" lift.

The truck doesn't see very many miles. Maybe 1000-1500 miles per year. On the highway it runs anywhere from 3000-3500rpm. I'm not sure spring life is a big issue. I don't plan on revving the engine past 4500.

I'd go with my last recommendation then.
210/214 112lsa+4(108 ICL), lift .595"/.559" with the #3012(210*)#3110(214*) lobes.
It'll have a IVC of 33, and -12* overlap so it'll run smooth.

I'd run a set of PAC 1211x beehive valve springs with this cam, mainly because of the more aggressive #3012(210*) intake lobes, and they'll be a direct swap with the factory springs so you can use the factory retainers and locks.

This hasn't been my experience. Maybe it has yours but I chose the LS1 Vette cam because it was closest to the Vinci HD Tow Stick which has received good reviews.
DUR @ .004" 262*/ 270*
DUR @ .050" 200*/ 208*
LIFT .502 / .502
LSA 115*


My choice is working out great for me. I also had the 317 heads ported for increase in the low and mid lifts. Truck specific porting is not real popular because it does sometimes impede with high lift flow. Working trucks owners shouldn't be overly concerned with high lift flow.
