okay guys, havent really got all my answers so ill just be blunt. i have a 2008 silverado RCSB 4.8l 4l60e. all stock format and have a list of parts im ready to purchase but the goal is 12 and i dont want to be let down. those of you who have a 12 second or faster ride please let me know what i need in order to get there. my thoughts were lt, ory-pipe, slp loudmouth, circle d 278mm 3200 stall, 4.10, cai , 150hp nitrous, and cam ? please help me. part numbers greatly appreciated

 

Don't forget either a built 60e or a 80e. Your trans will not last long if your building for power.

 

I'd think you would want more gear and a looser converter to get that 4.8L into the 12's. Probably a 218/218 or 220/220 cam. Take that with a grain of salt though and do a lot of searching. I'm sure you aren't the first one with these goals

 

just turbo it surprised it hasnt been said lmao

 

^^^ right on

Read my threads to see my results

 

Do a turbo kit and a built transmission.

 

Lt, ory, 4.10, 3600 circle d triple disk, 222/224 .566/.568 112lsa and a 100 shot..I have a buddy running this in his ex cab and ran a 12.6.

 

i saw a guy last season at heartland park with 150 shot headers and good rubber run a 12.6 no tuning or nuthin.

 

I think a tune 200 on a plate and some longtubes should get it done.

 

This gives me a little hope ,thanks for the cam specs too. does anyone have a part# on that cam shaft or opinions on it as well. Turbo is deffinately out of the budget right now. im looking at a 4 grand build not a max effort. this is a cruisen truck and i do ride it on weekends. wont be beating it and spraying very often just would like to know i can run with 12 second vehicls if need be. as far as the stock 4l60e , should it be fine with just the bolt ons, cam and tune i listed. will a shift kit or any cheaper parts help it last. i understand the nitrous(150) will be hard on it there for will be running n/a 99% of the time. Also does anyone have some traction bar part numbers <i cannot find them anywhere
