broke1 0 Report post Posted February 2, 2018 I know this forum is kind of dead but I also know Silverado SS guys know a thing or 2 about getting a heavy truck to lay down some ETs? Truck is a heavy AWD Escalade EXT....nv149/built 4l65 w/ PTC built TB stall,3.73 gears.Engine setup is: Gen 4 iron 6.2 (.065 over 6.0) 216/224 .551/.551 114+4 Howards cam(Vinci/Crane knock off) Advanced induction 226cc ported 799s Ls9 hesdgaskets w/ ARP Head bolts 11.3:1 compression w/ stock ls3 hyper pisons(I plan on running e85 and meth injection) Long tube headers and Corsa Touring(I know I need to get a true dual exhaust) ATI 4% is balancer All other bolt ons and good stuff And a MP112 w/ upgraded HE,upgraded 100mm idlers,HD tensioner,90mm J tube,etc. The reason for the high compression is I never planned on any kind of power adder(I know) but I ran up on a deal on a polished mp112 kit I couldnt pass up so here I am. Ive read a lot about the Lingenfelter GT2-3 cams(207/220 on a 118.5) holding the ET record when paired with a mp112 in a Silverado SS. The current cam is very mild in the 6.2 and peaks around 5800rpm. Will I really be giving up that much or anything not running the gt2-3? Im thinking the gains/driveability between the 2 would be minimal and Id be better off spending the $$$ on a dual exhaust setup like Speed Engineering sells.... I know I will be very limited on boost/timing so the right cam will be even more important. Thoughts? Quote Share this post Link to post Share on other sites
