thanks saved that page. surprised to see the LS at 107and 38 degrees overlap I though turbo cars liked wide LS 112-114 with would degrees overlap.I know the stock cam is good for some good HP.I see lots of cams out there from mild to wild.We don't emissions test here , my new TT chip has no EGR ,Though I would clean up my valve timing ,Bring the RPM up to 5500-5700.I was looking at only cams with 112LS Comp & Edelbrock and a few others. This is a week end cruiser weather permitting and about half a dozen trips to the strip a year,I have a new HP5857 BB billet wheel, down pipe. Should I stick with my gut and stay wit 112 There is a lot of people running 110 LS cams
