There you go.. 224/230 with a 112 LSA will give you the chop you want due to overlap. Degreed to 110 ICL will help get back some of the low end you'll lose.

I'm alot more conservative considering I like torque and off-the-line response. I got a Comp xr265hr15, degreed to 111, but I'd maybe consider a Texas Speed 220. Problem is, most LS camshafts come with like 115-117 LSA, which is not good for torque and also smoothes out the idle.

the comp thumpr cam 275thr7 is 219/233 lsa 109 says choppy/choppy idle ok with stock converter???

its so confusing chosing a cam, one guy says 220 other says 224 other says 219, im gonna go insane trying to figure this out! hahaha

Download camquest off of comp's website, and play around with it.

ok i will download that, but i do like the sound of the thumper says it has a choppy idle which is what i want and i can use it without upgrading the stall which my wallet likes! haha

Ever heard of the GM ASA cam? its got a choppy idle and makes good power in the upper RPM's

I would listen to Stunna considering he has run one of those cams. Dont get a thumper. Id go with either a tr220 or the one tyler is suggesting. But a converter is a must.

u need atleast a 3000 stall to run the thumper,and 4.10gears,power wouldnt kick in till 3500rpm,honestly truck felt faster with stock cam

yup,i shouldve gone with the 216/220,,but instead i got custom specs from allen:),sound of the thumper with power

Call Nelson and have them spec u out a cam. Thats gonna be ur best bet. If ur wantint to be fast ur gonna need a stall anyways so let nelson pick u out a combo unless all ur worried bout is sound..

well my truck is also a 5.3l not a 4.8l so im ahead anyways and a cam no matter what kind will make a gain, im also doing a tune obviously, headers and the new fast intake lsxrt which claims 25 hp, so i think not matter what cam along with tune headers and intake manifold im going to see some good power
