Don't cave
Hey, Screamin' 5.9 I like your plans. Dont put an auto behind that thing, stick with your ideas and make it happen. It wont be as fast or as consistent as a built auto, and it might break things, but so what! IT will be a blast to drive and defiantly plenty fast for playing around on the street. Ive never owned a automatic anything, so i understand the draw of a manual trans. As for the High rpm thing, 5000 is a little out there but low 4000s will be a great improvement over the 3000 rpm stock CR software and wont require any billet rods. the 12v rods are a good setup, factory bearings good too. Ati balancer, balanced rotating assembly, twin stock cp3s , 175-200 nozzles, 4500 RPM capable valve springs and push tubes are some of the basics. Tuning, machine work and engine assembly all have too be 110% to make things live at elevated RPMS . But keep in mind all this is just my opinion. Have fun with your build. Steve
