I have an '01 ECSB Z71, 4'' lift, 315/75R16s, brute force cold air, 3.73 rear, stock stall.

Based off of the following mods:

- GMPP LS6 Heads w/ Comp springs
- Typhoon intake w/ 85mm TB
- Comp 1.75 rockers/pushrods/lifters
- Pacesetter Long tube headers
- Flowmaster Supper 44 w/ 2.5 pipes
- Comp 3 way timing set

Which of the following cams would provide the BEST gain in Torque and HP (emphasis on torque) from low end through mid range without a sky high RPM powerband?
- Thunder Racing "Old Man Truck Cam" Duration @ .50" lift: 214/220 (int/exh) Valve lift: .600/.523 (int/exh) 115 LSA
- Crane Truck Cam #1449545 Duration @ .050" lift: 200/208 (int/exh) Valve lift: .502"/.502" (int/exh)
- COMP XFI G3 XFI 260 HR15 Truck Cam Duration @ .50" lift: 206/212 (int/exh) Valve lift: .513"/.520" (int/exh) 115 LSA
- COMP Tri-Power Xtreme TPX 254HR-16 Duration @ .50" lift: 202/212 (int/exh) Valve lift: .507"/.500" (int/exh) 116 LSA

I am well aware of other options such as gears and a higher stall. But as of now, all I want to do is fine the best cam for the setup I have. When I do, a tune will bring it all together.

Any help would be greatly appreciated.

Thanks

 

Have you took a look at the comp 212/218?

 

I've looked at so many I've lost count. But I'm always open to sugestions from anyone who has found something that works great in a 5.3....

 

I would personally go with a 212/218 114lsa

 

well one thing to be careful about is your 1.75 rockers, I know your old man cam has a very agressive ramp rate, tr recomends the use of 1.7's. I don't know if that little difference would cause you problems or not. I have herd that that cam is a torque monster though!

 

there's always the xr259 from Comp: 206*/212* with 52x"/52x" lift

 

Edit...........

 

I would go with the 212/218 like mentioned above

 

I would go with a high lift 212/218 on a 114 lsa, like .58x lift. Shoot PatrickG a pm, he'll spec you one for around $25. $25 spent is better than guessing about it.

 

1.7s are recomended, but 1.75s are the limit. If you try and run 1.8 you will have problems....
