Default Poll: Which cam for LS1 swap?

Which cam for my LS1 build-up w/stage 2 5.3 Patriot heads?

FMS Cam Lobes:
-(F2)224/224-.588/.588-112
or
-221/221-.575/.575-112
or
-218/218-.575/.575-112


My goal is good torque all over the power-band, especially down low-saying that I mean I still want as much torque as a stock LS1 in the very low rpms.. I tow a big ATV and a fishing boat. Other mods with be all bolt-ons I have now, including the 3.90 gears. I also plan on adding a 2400 stall later on. I just want something that won't "Bog Down" in the low rpms (800-1500rpms).

I've been looking at dyno charts with the "smaller" LS1 cams, like the 220/220, 224/224, etc. These things are making around 300-315rwtq at 2200-2500rpms! That's more than my peak at 4000rpms! What do you guys think? The 224/224 is what I really want to run, but I'm scared I might loose to much low-end in my ext. cab. Is the 224/224 okay for what I want or should I consider going a little bit smaller?

I vote either the F2 or a TR224. That cam has proven itself many a times. Scream loves his TR224 in his LS1. You should hit him up and chat with him about the powerband on it. But from what I have seen there havent been any complaints on the 224. You might lose some down low with that cam. But you might also want a bit more converter for it too. But in a heavy truck it might be a good idea to kick things down a bit and try the 221/221 or a 222/222. But again, its not much smaller than a 224.

Thats the cam that I have in my LS1. Hopefully if everything goes good, I should see how it performs after labor day weekend.

Id go with the f2 the only time you'll see rpms under 1200 is when you idling just bump up the tcc lockup speeds down low in each gear and viola

I love my TR224. It seems like it pulls hard throughout the entire RPM range. Im shifting at 6400.
