All, I am finally ready to pull the trigger on my engine build and wanted to gather some opinions from the experts on here. The build I currently have pending is as follows: 2003 Silverado SS with 67,000 miles JBA Long Tube Headers Full Custom Borla dual Exhaust with X-Pipe Whipple 2.3 kit Cam KitCam 227/234 .614/.576 113+2 Springs, retainers, etc Pushrods Fuel pump booster Custom Dyno Tune Everything else will remain stock My goals are 550-600hp & 500-550ft-lbs torque at the crank. 100% daily driveable. I am not planning to replace the torque converter. My main concern is the cam specs above. I have been told not to go above .551 lift on the LQ9. Anything higher than that will have clearance issues. The builder I am planning to have do the work for me recommended the specs listed above. Should I be alarmed? Thanks in advance.
