Cam Motion LLR + Pro1 LS3 Heads = 707 FWHP
#22
When i first put the engine in, the raceweight was #3600 with an empty fuel tank and no nitrous bottle. With about 5 gallons of fuel and a full nitrous bottle, a little over #3650. Now, that I am replacing the TH200 with a 4L80, it is likely going to be over #3700 with some gas and a nitrous bottle. The 6 point, Strange S60 and 4L80 are porking her up. Good thing I went with an aluminum block or she would be really portly.

I expect this LLR to be like my last one. I adjusted the valves once after a couple weeks of driving and never messed with them again. I know one LLR owner who had 20,000 miles on his and has never touched the valve adjusters. So, unless I hear something unusual, not until it is time for valve springs.
