I am building my first twin turbo eng, been reading a lot on this forum and its helped a lot. I am running a 2005 5.3 with 20 over weisco -10 cc pistons and some 6.0 heads with a ls9 headgasket for a 8.1 compression. I am running stock rods, stock crank, but up graded to head studs, high pressure oil pump, new billet cam, new lifters, new timing set, a set of 58 mm turbos, stock intake. now I am at a point to try and figure fuel injectors, fuel pump, and electronics. I am running a built 4L80 tranny with a 3000 stall. any input would be great going in a 2400lb to 2600lb 34 dodge panel rat rod. running a 350 rear gear with 29 inch tall tires. hoping to get between 550 hp to 600 hp any and all advise would be great. thanks.
