[QUOTE="RedVenom48, post: 16087425, member: 166576"] In 2019, I plan on doing a strengthening of my 2011 Shortblock to handle boost. I went back and forth on whether I should just buy a big boy blower and be done with it or do what I know is the right way to get there. After getting a chance to meet [USER=14133]@Willie[/USER] personally this past summer, I had a HUGE desire to say F it and go right for a 4.2 KB. His car is nothing less than incredible and his beast of a KB is a shit-eating grin-maker the second it starts up! After cooling my jets a bit, I realized theres no point in having a big blower if I always have a question about the rods holding up in the back of my head. Fuel will be 100 octane race gas from the pump. Goals for build: Reliable 900-1000 rwhp powered (eventually) by a KB 4.7L or a Whipple 4.5L. Reliable use of WOT Box 2 step launch controller when at the drag strip 7000 rpm redline at the drag strip Install headers Install k-member spacer kit (decided I want to use the factory hood) CAM CHOP :D Idea is to build the engine first, then go for the blower. Per a call to Mahle, the 2011-2012 GT500 pistons can handle 1000 at the wheels. Same pistons in the 2012 CJ are in the 2011-2012 GT500. Same crank too, but the GT500 rods are obviously the famous Ford PM rods. So here's the current idea: Short Block: Oliver Speedway 5.4L forged rods with ARP fasteners and rotating assembly balance King crank and rod bearings ARP 5.4L Aluminum main stud kit Check and perform crank bore align hone with stud installation MMR Billet oil pump gears ARP head stud kit Accufab 8mm tensioner arm pivot pins (purchased) Kinetik Motorsports Crank Saver ARP stud kit (purchased) Timing: Cloyes billet cam gear secondary sprockets (purchased) OEM primary cam gears, chains and tensioners (purchased) Accufab Cam spacer kit ARP Cam Bolt kit MMR billet secondary chain tensioner kit and MMR XHD Secondary chains MMR billet primary crank gear MMR Billet tensioner arms Cams: ???????????????? Part of me wants the get the JDM S/S cam kit. I know there are many who use and love the S/S cams. Problem is that money is an object and at some point, I have to set a limit. Ive been thinking very hard about the Billet Pro Shop Bullet Racing cams. What I really like about them is that they work and are NSR. I know L&M make a set of NSR GT500 cams as well. The 13-14 GT500 (Ford GT) cams are a good improvement over the 07-12, but if Im replacing them I want some cam chop. :D Any advice? The car wont be used in competition, and street manners will still matter. I want to chase ETs and make some pulls in Mexico. [/QUOTE]
