You haft to pay if you want to play!!

 

I find my self thinking about this all the time. The golden rule is that if we wanna make ~500 wheel or wanna rev up to 6k, that these dod lifters are a weak dangerous point. When I'm ready to turn mine up I'll be swapping for ls7 lifters and prolly a boost cam.

Why go through all the labor and money to make power and not have it reliable or always worried about laying into it. Right now I barely go into v4 mode in my daily commute but when I jump on the thruway it kicks right in and works great (except the drone). Average 20 mpg at a reasonable speed and load. Where in v8 mode I might be stuck around 17. This is where logic comes in. If u want a 500 hp turbo full size truck then you can't expect crazy mileage and stock parts to hold up to a combo thats making 300 more hp than it was designed for. Better safe than sorry.

 

i have a 2012 rcsb work truck 2wd. im expecting about 350 rwhp with 5.3 stock longblock comp 689-421-13 dod/vvt camshaft.i already have knn dropin airraid tube ported 90mm tb lsxrt102mm intake kooks longtubes with catted y 3 inch single w 18inch glasspack turndown before axle. slp udp yalla terra 1.8 ultralite shaft mount rockers tuned by area47. he knows how to make good power with vvt and turning off the dod lifters!

 

good luck with that
