Re: Which cam is best for low-end grunt?
 

I don't think there is any one particular cam that is absolutly "best" for low-end grunt, but the TR220 has exceptional throttle response and LOTS of low-end grunt. Get it in a 114 LSA and it will still bring the total power band up to about 6,300-6,400 revs (as long as you have a very free flowing exhaust system). The 112 LSA will take a little too much away at the higher revs.

The heavy hitting larger cams will make a few more ponies at high revs, but tend to be a little soft at low rpm due to there greater overlap.

Ron,

Unlike the old SB Chev, the LS1 heads flow so well both on the intake and exhaust sides that a split cam is not really needed. The single duration cams appear to work very well and idle a bit smoother than the splits.

Just order a TR220 from Thunder. Ask for it in the 114 LSA. It will come with an Intake Centerline (IC) of 110 which will give it 4 degrees of advance if installed dot-to dot on the timing gears.

The 4 degrees of ground-in advance gives the cam quicker low rpm throttle response (tip-in) than if it had no advance at all.

I have a similar cam in my f-body with ported ls6 heads...

...Indian's cam is a good recommendation for a low-end street motor

Another vote here for the TR220. Makes loads of power in my car and has a great idle too.

You guys dont think he should go with the lower lsa since he is building it for a truck and not for higher rpms?

My TR220 is on a 112LSA and it idles great. Don't be afraid of the 112LSA on a small cam, it doesn't affect the idle that much.

The 2001-2002 stock LS1 cam is probably the best for low-end grunt. To get even more power without winding up, throw a Wipple charger on there. Supercharging works great on trucks.

I gained power throughout the RPM with my little 218/224 .563/.569 cam....Great lowend punch, much more than the stocker.....

well call me crazy but thehot cam pulls like a beast, not a 224 224 110 strait up would be awsome too :cool:

Re: Which cam is best for low-end grunt?
 

If you believe in computer simulation info, a small duration cam with a tight LSA like the CompCams 206/212 112 or Crane PowerMax 208/216 113 shows more torque at 2000 rpm (start of the dyno curve) than a stock 2002 LS1 cam. The ICL and valve timing events look close to optimum for a SBC. I wonder if those values hold true for the long-rod LS1?

I just stuck an LS1/T56 in my 01 Pickup, I also used an 02/03 LS6 cam and advanced the cam timing 2 deg. but I am not sure I did the right thing, I haven't been able to drive it yet because a new driveshaft is on order but the truck wants to idle around 400 rpm's which is to low, according to street and performance I shouldn't have done that so before you do something like that research it out better.

One of my personal favorites for a stump puller is the Comp Cams 212/218. I would personally go for the high lift version which is about .560 total lift. With a set of CC 918 springs, it would be very reliable.
This would make an awesome street truck cam. Near stock driveability and capable of running well on the stock tuning. You could easily custom tune with a Predator hand held. Would be well matched to the stock intake.
Power range is 1400-6000.

With a 3000+ stall you don't need 1960's big block torque at 1300 rpm. ;) You need good torque strating at 2500+ rpm. I agree that a TR 220 114 with a 110 I/C will provide a lot of midrange gain and will work nicely with your set-up.

This is how the TR220/114 cam dyno'd in my car with headers, bolt-ons and stock heads. Basically, >300 ft/lb of torque everywhere, and above 350 ft/lb from 3300-5400. Hp is pretty flat at 380 rwhp from 5600-6500.
